Performance
Designed to start and work at an ambient as low as -40°C, but may not meet operational limits until above -5°C
The maximum operational ambient is reduced in Europe in order to meet certain power cord maximum ratings of 70C. The maximum operational
ambient where 70C rated power cords are utilized is reduced to 60C until testing demonstrates that a higher level is acceptable. At high input
voltage (530VAC), the maximum temperature rating is reduced to 70C.

Response to input fluctuations
T1 – ride through time – 0.5 to 1 cycles [ 10 – 20ms] VOUT remains within regulation – load dependent
T2 – hold up time - 15ms – VOUT stays above 40VDC
T3 – delay time – 10s – from when the AC returns within regulation to when the output starts rising in I2C mode
T4 – rise time - 120ms – the time it takes for VOUT to rise from 10% to 90% of regulation in I2C mode
T5 – power good warning – 3ms – the time between assertion of the PG signal and the output decaying below 40V DC.
T6 – hold up time of the 5VAUX output @ full load – 1s – from the time AC input failed
T7 – rise time of the 5VAUX output - 3.65ms – 5VAUX is available at least 450ms before the main output is within regulation

between 1kΩ and 5kΩ should be present between this pin and
Vout ( - ).
Control and Status
The power supply provides three means for monitor/control:
analog, PMBus™, or the GE Galaxy-based RS485 protocol.
Details of analog control and the PMBus™ based protocol are
provided in this data sheet. GE will provide separate
application notes on the Galaxy RS485 based protocol for
users to interface to the power supply. Contact your local GE
representative for details.
Control hierarchy: Some features, such as output voltage, can
be controlled both through hardware and firmware. For
example, the output voltage is controlled both by a signal pin
(Vprog) and a PMBus command, (OPERATION) .
Using output voltage as an example; the Vprog signal pin has
ultimate control of the output voltage until the Vprog is either
> 3VDC or a no connect. When the programming signal via
Vprog is either a no connect or > 3VDC, it is ignored, the output
voltage is set at its nominal 54VDC.
Unless otherwise noted, the Vprog signal pin controls the
output voltage set point (if it is connected) until a firmware
command is executed. Once a firmware command to change
the output voltage has been executed, the signal pin is
ignored. [In the above example, the power supply will no
longer ‘listen’ to the Vprog pin if the OPERATION command has
been executed.]
Device address in I2C mode: Address bits A3, A2, A1, A0 set
the specific address of the µP in the power supply. With these
four bits, up to sixteen (16) power supplies can be
independently addressed on a single I²C bus. These four bits
are configured by two signal pins, Unit_ID and Rack_ID. The
least significant bit x (LSB) of the address byte is set to either
write [0] or read [1]. A write command instructs the power
supply. A read command accesses information from the
power supply.

Unit_ID: Up to 10 different units are selectable.
Signal Reference: Unless otherwise noted, all signals, the
standby output, and I2C communications are referenced to
Logic_GRD. See the Signal Definitions Table at the end of this
document for further description of all the signals.
Logic_GRD is capacitively coupled to Frame_GRD inside the
power supply. The maximum voltage differential between
Logic_GRD and Frame_GRD should be less than 100VDC. It is
assumed that the end user will connect Logic_GRD to his
digital ground reference in his system.
Logic_GRD is isolated from the main output of the power
supply.
(Note that RS485 communications is referenced to Vout(-),
main power return of the power supply).

Global Broadcast: This is a powerful command because it
instruct all power supplies to respond simultaneously. A read
instruction should never be accessed globally. The power
supply should issue an ‘invalid command’ state if a ‘read’ is
attempted globally.
For example, changing the ‘system’ output voltage requires
the global broadcast so that all paralleled power supplies

change their output simultaneously. This command can also
turn OFF the ‘main’ output or turn ON the ‘main’ output of all
power supplies simultaneously. Unfortunately, this command
does have a side effect. Only a single power supply needs to
pull down the ninth acknowledge bit. To be certain that each
power supply responded to the global instruction, a READ
instruction should be executed to each power supply to verify
that the command properly executed. The GLOBAL
BROADCAST command should only be executed for write
instructions to slave devices.
Alert Response Address (ARA): This feature enables the
‘master’ to rapidly determine which ‘slave’ power supply
triggered the SMBAlert signal without having to poll each
power supply one at a time. During normal operation the
power supply activates (pulls down LO) the Alert signal line
indicating that it needs attention when a ‘state’ change
occurs. The master can determine who pulled the ‘alert’ line
by sending out the alert-response-address, address 12b, with
a ‘read’ instruction. If the power supply triggered the ‘alert’ it
should respond back with its address. The instruction takes
the form below;

margin setting. As an example, adding a resistor between Vprog
and Logic_GRD is an effective way of changing the factory set
point of the power supply to whatever voltage level is desired
by the user during initial start-up.
The Vprog pin level should be set by a divider from 3.3Vdc to
Logic_GRD external to the power supply as shown in the
graph. Programming can be accomplished either by a resistor
divider or by a voltage source injecting a precision voltage
level into the Vprog pin. Above 3Vdc the power supply sets
the output to its default state. If Vprog feature is not used, this
signal should be pulled up to the 5VA output with a 10k
resistor.
An analog voltage on this signal can vary the output voltage
from 44Vdc to 58Vdc.
If during the ARA response multiple power supplies send out
their addresses, then the actual address received by the
master is the lowest address from the combinations of those
power supplies that responded.
Factory default setting driven by Vprog
The ‘my address’ field contains the address of the power
supply in the 7 most significant bits (msb) of the byte. The lsb
of the byte is a don’t care, it could be a 0 or a 1. For more
information refer to the SMBus specification
The µC needs to read the actual my address data byte that is
sent back to the master. If the my address data byte agrees
with the address of this unit, then, and only then, the µC
needs to clear (de-assert) its Alert# signal. Thus, the power
supply whose address has been sent out gets de-asserted
from the joint Alert# line.
If the Alert# line is still asserted, the host should send out an
ARA request again and find out who else asserted Alert#. This
process needs to continue until the Alert# is released which is
a clear indication that all power supplies that asserted Alert#
have had their status states read back.
Voltage programming (Vprog): Hardware voltage programming
controls the output voltage until a software command to
change the output voltage is executed. Software voltage
programming permanently overrides the hardware margin
setting and the power supply no longer listens to any
hardware margin settings until power to the controller is
interrupted, for example if input power or bias power is
recycled.
When bias power is recycled to the controller the controller
restarts into its default configuration, programmed to set the
output as instructed by the Vprog pin. Again, subsequent
software commanded settings permanently override the

Load share (Ishare): This is a single wire analog signal that is
generated and acted upon automatically by power supplies
connected in parallel. Ishare pins should be connected to each
other for power supplies, if active current share among the
power supplies is desired. No resistors or capacitors should
get connected to this pin.
ON/OFF: Controls the main 54VDC output when either analog
control or PMBus protocols are selected, as configured by the
Protocol pin. This pin must be pulled low to turn ON the
power supply. The power supply will turn OFF if either the
ON/OFF or the Interlock pin is released. This signal is
referenced to Logic_GRD. Note that in RS485 mode this pin is
ignored.
Interlock: This is a shorter pin utilized for hot-plug
applications to ensure that the power supply turns OFF before
the power pins are disengaged. It also ensures that the power
supply turns ON only after the power pins have been engaged.
Must be connected to V_OUT ( - ) for the power supply to be
ON.
8V_INT: Single wire connection between modules, provides
redundant bias to the DC/DC control circuitry of an
unpowered module.

the power supply to notify the system controller that a power

supply is physically present in the slot. This signal pin is pulled
down to Logic_GRD by the power supply
Power Good Warning (PG#): This signal is HI when the main
output is being delivered and goes LO if the main output is
about to decay below regulation. Note that should a
catastrophic failure occur, the signal may not be fast enough
to provide a meaningful warning. PG# also pulses at a 1ms
duty cycle if the unit is in overload.
Fault#: A TTL compatible status signal representing whether a
Fault occurred. This signal needs to be pulled HI externally
through a resistor. This signal goes LO for any failure that
requires power supply replacement. These faults may be due
to:
•
•
•

generate the correct PEC byte for all transactions, and check
the PEC byte returned by the power supply.
The Alert# response protocol (ARA) whereby the PMBus
Master can inquire who activated the Alert# signal is also
supported. This feature is described in more detail later on.
Non-volatile memory is used to store configuration settings.
Not all settings programmed into the device are automatically
saved into this non-volatile memory. Only those specifically
identified as capable of being stored can be saved. (see the
Table of Commands for which command parameters can be
saved to non-volatile storage).
Non-supported commands: Non supported commands are
flagged by setting the appropriate STATUS bit and issuing an
SMBAlert# to the ‘host’ controller. If a non-supported read is
requested the power supply will return 0x00h for data.
Over-temperature shutdown
Over-voltage shutdown
Internal Power Supply Fault
Data out-of-range: The power supply validates data settings
and sets the data out-of-range bit and SMBAlert# if the data
is not within acceptable range.
Serial Bus Communications
The I²C interface facilitates the monitoring and control of
various operating parameters within the unit and transmits
these on demand over an industry standard I²C Serial bus.
All signals are referenced to ‘Logic_GRD’.
Pull-up resistors: The clock, data, and Alert# lines do not have
any internal pull-up resistors inside the power supply. The
customer is responsible for ensuring that the transmission
impedance of the communications lines complies with I2C and
SMBus standards.
Serial Clock (SCL): The clock pulses on this line are generated
by the host that initiates communications across the I²C Serial
bus. This signal needs to be pulled HI externally through a
resistor as necessary to ensure that rise and fall time timing
and the maximum sink current is in compliance to the I²C
/SMBus specifications.
Master/Slave: The ‘host controller’ is always the MASTER.
Power supplies are always SLAVES. SLAVES cannot initiate
communications or toggle the Clock. SLAVES also must
respond expeditiously at the command of the MASTER as
required by the clock pulses generated by the MASTER.
Clock stretching: The ‘slave’ µController inside the power
supply may initiate clock stretching if it is busy and it desires
to delay the initiation of any further communications. During
the clock stretch the ‘slave’ may keep the clock LO until it is
ready to receive further instructions from the host controller.
The maximum clock stretch interval is 25ms.
The host controller needs to recognize this clock stretching,
and refrain from issuing the next clock signal, until the clock
line is released, or it needs to delay the next clock pulse
beyond the clock stretch interval of the power supply.
Note that clock stretching can only be performed after
completion of transmission of the 9th ACK bit, the exception
being the START command.
Serial Data (SDA): This line is a bi-directional data line. This
signal needs to be pulled HI externally through a resistor as
necessary to ensure that rise and fall time timing and the
maximum sink current is in compliance to the I²C /SMBus
specifications.
Digital Feature Descriptions
PMBus™ compliance: The power supply is fully compliant to
the Power Management Bus (PMBus™) rev1.2 requirements.

I²C Bus Lock-Up detection: The device will abort any
transaction and drop off the bus if it detects the bus being
held low for more than 35ms.
Communications speed: Both 100kHz and 400kHz clock rates
are supported. The power supplies default to the 100kHz clock
rate.

GP100H3M54TEZ Global Platform Line High Efficiency Power Supply
3-380/480VAC Input; Default Outputs: ±54/52VDC @ 6000W, 5VDC @ 10W
Packet Error Checking (PEC): The power supply will not
respond to commands without the trailing PEC. The integrity
of communications is compromised if packet error correction
is not employed. There are many functional features,
including turning OFF the main output, that require validation
to ensure that the correct command is executed.
PEC is a CRC-8 error-checking byte, based on the polynomial
C(x) = x8 + x2 + x + 1, in compliance with PMBus™
requirements. The calculation is based in all message bytes,
including the originating write address and command bytes
preceding read instructions. The PEC is appended to the
message by the device that supplied the last byte.
Re-initialization: The I2C code is programmed to re-initialize if
no activity is detected on the bus for 5 seconds. Reinitialization is designed to guarantee that the I2C µController
does not hang up the bus. Although this rate is longer than the
timing requirements specified in the SMBus specification, it
had to be extended in order to ensure that a re-initialization
would not occur under normal transmission rates. During the
few µseconds required to accomplish re-initialization the I2C
µController may not recognize a command sent to it. (i.e. a
start condition).
Alert#: The power supply can issue Alert# driven from either
its internal micro controller (µC) or from the I2C bus master
selector stage. That is, the Alert# signal of the internal µC
funnels through the master selector stage that buffers the
Alert# signal and splits the signal to the two Alert# signal pins
exiting the power supply. In addition, the master selector
stage signals its own Alert# request to either of the two Alert#
signals when required.
Read back delay: The power supply issues the Alert#
notification as soon as the first state change occurred. During
an event a number of different states can be transitioned to
before the final event occurs. If a read back is implemented
rapidly by the host a successive Alert# could be triggered by
the transitioning state of the power supply. In order to avoid
successive Alert# s and read back and also to avoid reading a
transitioning state, it is prudent to wait more than 2 seconds
after the receipt of an Alert# before executing a read back.
This delay will ensure that only the final state of the power
supply is captured.
The µC driven Alert# signal informs the ‘master/host’
controller that either a STATE or ALARM change has occurred.
Normally this signal is HI. The signal will change to its LO level
if the power supply has changed states and the signal will be
latched LO until the power supply receives a ‘clear_faults’
instruction.
Successive read backs: Successive read backs to the power
supply should not be attempted at intervals faster than every
one second. This time interval is sufficient for the internal
processors to update their data base so that successive reads
provide fresh data.
The signal will be triggered for any state change, including the
following conditions;
•
VIN under or over voltage
•
Vout under or over voltage
•
IOUT over current
•
Over Temperature warning or fault
•
Fan Failure
•
Communication error
•
PEC error
•
Invalid command
•
Internal faults
•
Both Alert#_0 and -1 are asserted during power up to
notify the master that a new power supply has been
added to the bus.
The power supply will clear the Alert# signal (release the
signal to its HI state) upon the following events:
•
Receiving a CLEAR_FAULTS command
•
Bias power to the processor is recycled
Two independent I2C lines provide true communications bus
redundancy and allow two independent controllers to
sequentially control the power supply. For example, a short or
an open connection in one of the I2C lines does not affect
communications capability on the other I2C line. Failure of a
‘master’ controller does not affect the power supplies and the
second ‘master’ can take over control at any time.
Conceptually, a Digital Signal Processor (DSP) referenced to
Vout(-) of the power supply provides secondary control. A
Bidirectional Isolator provides the required isolation between
power GRD, Vout(-) and signal GRD (Logic_GRD). A secondary
micro controller provides instructions to and receives
operational data from the DSP. The secondary micro
controller also controls the communications over two
independent I2C lines to two independent system controllers.
I2C_0
The power supply will re-assert the Alert line if the internal
state of the power supply has changed, even if that
information cannot be reported by the status registers until a
clear_faults is issued by the host. If the Alert asserts, the host
should respond by issuing a clear_faults to retire the alert line
(this action also provides the ability to change the status
registers). This action triggers another Alert assertion because
the status registers changed states to report the latest state of
the power supply. The host is now able to read the latest
reported status register information and issue a clear_faults to
retire the Alert signal.

I2C_1
The secondary micro controller is designed to default to I2C_0
when powered up. If only a single system controller is utilized,
it should be connected to I2C_0. In this case the I2C_1 line is
totally transparent as if it does not exist.
If two independent system controllers are utilized, then one of
them should be connected to I2C_0 and the other to I2C_1.

Status and Alarm registers: The registers are updated with
the latest operational state of the power supply. For example,
whether the output is ON or OFF is continuously updated with
the latest state of the power supply. However, alarm
information is maintained until a clear_faults command is
received from the host. For example, the shutdown or
OC_fault bits stay in their alarmed state until the host clears
the registers.
A clear_faults clears all registers. If a fault still persists after
the clear_faults is commanded, the register bit annunciating
the fault is reset again.

GP100H3M54TEZ Global Platform Line High Efficiency Power Supply
3-380/480VAC Input; Default Outputs: ±54/52VDC @ 6000W, 5VDC @ 10W
Command Descriptions
Operation (0x01) : By default the Power supply is turned ON
at power up as long as Power ON/OFF is active LO. The
Operation command is used to turn the Power supply ON or
OFF via the PMBus. The data byte below follows the
OPERATION command.
FUNCTION
DATA BYTE
Unit ON
0x80
Unit OFF
0x00
Clear_faults (0x03): Clears all STATUS and FAULT registers
and resets the Alert# line of the I2C side in control. The I2C
side not in control cannot clear registers in the power supply.
This command is always executable.
If a fault still persists after the issuance of the clear_faults
command, the specific registers indicating the fault first clears
but then get set again to indicate that the unit is still in the
fault state.
WRITE_PROTECT register (0x10): Used to control writing to
the PMBus device. The intent of this command is to provide
protection against accidental changes. All supported
commands may have their parameters read, regardless of the
write_protect settings. The contents of this register cannot be
stored into non-volatile memory using the Store_user_code
command. The default setting of this register is
enable_all_writes, write_protect 0x00h. The write_protect
command must always be accepted.
DATA BYTE
00
80
40
Restore_Default_All (0x12): Restores all register values and
responses to the default parameters set in the power supply.
The factory default cannot be changed.
Restore_default_code (0x14): Restore only a specific register
parameter to the factory default parameters set in the power
supply.
Store_user_code (0x17): Changes the user default setting of a
single register. In this fashion some protection is offered to
ensure that only those registers that are desired to be
changed are in fact changed.
Restore_user_code (0x18): Restores the user default setting
of a single register.
Vout_mode (0x20): This is a ‘read only’ register. The upper
three bits specify the supported data format, in this case
Linear mode. The lower five bits specify the exponent of the
data in two’s complement binary format for output voltage
related commands, such as Vout_command. These
commands have a 16 bit mantissa. The exponent is fixed by
the module and is returned by this command.
August 14, 2018
Bits [7:5]
Bits [4:0] (exponent)
Linear
000b
xxxxxb
Vout_Command (0x21) : Used to dynamically change the
output voltage of the power supply. This command can also
be used to change the factory programmed default set point
of the power supply by executing a store-user instruction that
changes the user default firmware set point.
The default set point can be overridden by the Vprog signal
pin which is designed to override the firmware based default
setting during turn ON.
To RESET the power supply cycle the power supply OFF, wait
at least 2 seconds, and then turn back ON. All alarms and
shutdowns are cleared during a restart.
FUNCTION
Enable all writes
Disable all writes except write_protect
Disable all writes except write_protect and
OPERATION
Mode
In parallel operation, changing the output voltage should be
performed simultaneously to all power supplies using the
Global Address (Broadcast) feature. If only a single power
supply is instructed to change its output, it may attempt to
source all the required power which can cause either a power
limit or shutdown condition.
Software programming of output voltage permanently
overrides the set point voltage configured by the Vprog signal
pin. The program no longer looks at the ‘Vprog pin’ and will
not respond to any hardware voltage settings. If power is
removed from the µController it will reset itself into its default
configuration looking at the Vprog signal for output voltage
control. In many applications, the Vprog pin is used for
setting initial conditions, if different that the factory setting.
Software programming then takes over once I2C
communications are established.
To properly hot-plug a power supply into a live backplane, the
system generated voltage should get re-configured into either
the factory adjusted firmware level or the voltage level
reconfigured by the margin pin. Otherwise, the voltage state
of the plugged in power supply could be significantly different
than the powered system.
Voltage margin range: 42VDC – 58 VDC.
A voltage programming example: The task: set the output
voltage to 50.45VDC
This power supply supports the linear mode of conversion
specified in the PMBus™ specification. The supported output
voltage exponent is documented in the Vout_mode (0x20)
command. The exponent for output voltage setting is 2-9 (see
the PMBus™ specification for reading this command).
Calculate the required voltage setting to be sent; 50.45 x 29 =
25830. Convert this decimal number into its hex equivalent:
64E6 and send it across the bus LSB first and then MSB; E664
with the trailing PEC.
Vin_ON (0x35): This is a ‘read only’ register that informs the
controller at what input voltage level the power supply turns
ON. The default value is tabulated in the data section. The
value is contingent on whether the power supply operates in
the low_line or high_line mode.
Vin_OFF (0x36): This is a ‘read only’ register that informs the
controller at what input voltage level the power supply turns
OFF. The default value is tabulated in the data section. The
value is contingent on whether the power supply operates in
the low_line or high_line mode.

3-380/480VAC Input; Default Outputs: ±54/52VDC @ 6000W, 5VDC @ 10W
Fan_config_1_2 (0x3A) : This command requires that the fan
speed be commanded by duty cycle. Both fans must be
commanded simultaneously. The tachometer pulses per
revolution is not used. Default is duty cycle control.
Fan_command_1 (0x3B): This command instructs the power
supply to increase the speed of both fans above what is
internally required. The transmitted data byte represents the
hex equivalent of duty cycle in percentage, i.e. 100% = 0 x
64h. The command can increase or decrease fan speed. An
incorrect value will result in a ‘data error’.
Sending 00h tells the power supply to revert back to its
internal control.
Vout_OV_fault_limit (0x40): Sets the value at which the main
output voltage will shut down. The default OV_fault value is
set at 60Vdc. This level can be permanently changed and
stored in non-volatile memory.
Vout_OV_fault_response (0x41): This is a ‘read only’ register.
The only allowable state is a latched state after three retry
attempts.
An overvoltage shutdown is followed by three attempted
restarts, each successive restart delayed 1 second. If within a
1 minute window three attempted restarts failed, the unit will
latch OFF. If less than 3 shutdowns occur within the 1 minute
window then the count for latch OFF resets and the 1 minute
window starts all over again. This performance cannot be
changed.
Restart after a latched state: Either of four restart
mechanisms is available;
•
The hardware pin ON/OFF may be cycled OFF and then
ON.
•
The unit may be commanded to restart via i2c through
the Operation command by first turning OFF then turning
ON .
•
The third way to restart is to remove and reinsert the
unit.
•
The fourth way is to turn OFF and then turn ON ac power
to the unit.
A successful restart clears all STATUS and ALARM registers.
A power system that is comprised of a number of power
supplies could have difficulty restarting after a shutdown
event because of the non-synchronized behavior of the
individual power supplies. Implementing the latch-off
mechanism permits a synchronized restart that guarantees
the simultaneous restart of the entire system.
A synchronous restart can be implemented by;
•
•
•
Issuing a GLOBAL OFF and then a GLOBAL ON command
to all power supplies
Toggling Off and then ON the ON/OFF signal, if this signal
is paralleled among the power supplies.
Removing and reapplying input commercial power to the
entire system.
The power supplies should be OFF for at least 20 – 30 seconds
in order to discharge all internal bias supplies and reset the
soft start circuitry of the individual power supplies.
August 14, 2018
An overvoltage shutdown is followed by three attempted
restarts, each successive restart delayed 1 second. If within a
1 minute window three attempted restarts failed, the unit will
latch OFF. If less than 3 shutdowns occur within the 1 minute
window then the count for latch OFF resets and the 1 minute
window starts all over again. This performance cannot be
changed.
Vout_OV_warn_limit (0x42): Sets the value at which a
warning will be issued that the output voltage is too high. The
default OV_warn limit is set at 56Vdc. Exceeding the warning
value will set the Alert# signal. This level can be permanently
changed and stored in non-volatile memory.
Vout_UV_warn_limit (0x43): Sets the value at which a
warning will be issued that the output voltage is too low. The
default UV_warning limit is set at 41Vdc. Reduction below the
warning value will set the Alert# signal. This level can be
permanently changed and stored in non-volatile memory.
Vout_UV_fault_limit (0x44): Sets the value at which the
power supply will shut down if the output gets below this
level. The default UV_fault limit is set at 39Vdc. This register
is masked if the UV is caused by interruption of the input
voltage to the power supply. This level can be permanently
changed and stored in non-volatile memory.
Vout_UV_fault_response (0x45): Sets the response if the
output voltage falls below the UV_fault_limit. The default
UV_fault_response is restart (0xC0).
Iout_OC_fault_limit (0x46): Sets the value at which the power
supply will shut down. The default OC_fault_limit is
contingent on whether the power supply operates in the
low_line or high_line mode. The default level can be
permanently changed and stored in non-volatile memory.
Which level is changed is contingent on the input voltage
applied to the power supply at the time the change takes
place.
Iout_OC_fault_response (0x47): Sets the response if the
output overload exceeds the OC_Fault_limit value. The default
OC_fault_response is hiccup (0xF8). The only two allowable
states are latched (0xC0) or hiccup. The default response
state can be permanently changed and stored in non-volatile
memory. The response is the same for both low_line and
high_line operations.
Iout_OC_warn_limit (0x4A): Sets the value at which the
power supply issues a warning that the output current is
getting too close to the shutdown level. The default level can
be permanently changed and stored in non-volatile memory.
Which level is changed is contingent on the input voltage
applied to the power supply at the time the change takes
place.
OT_fault_limit (0x4F): Sets the value at which the power
supply responds to an OT event, sensed by the dc-sec sensor.
The response is defined by the OT_fault_response register.

Read back Descriptions
Single parameter read back: Functions (except VIN, IIN) can be
read back one at a time using the read_word_protocol with
PEC. A command is first sent out notifying the slave what
function is to be read back followed by the data transfer.
Analog data is always transmitted LSB followed by MSB. A NA
following the PEC byte signifies that the transmission is
complete and is being terminated by the ‘host’.

Manufacturer-Specific PMBusTM Commands
Many of the manufacturer-specific commands read back more
than two bytes. If more than two bytes of data are returned,
the standard SMBusTM Block read is utilized. In this process,
the Master issues a Write command followed by the data
transfer from the power supply. The first byte of the Block
Read data field sends back in hex format the number of data
bytes, exclusive of the PEC number, that follows. Analog data
is always transmitted LSB followed by MSB. A No-ack following
the PEC byte signifies that the transmission is complete and is
being terminated by the ‘host’.
Mfr_Specific Status and alarm registers: The content and
partitioning of these registers is significantly different than the
standard register set in the PMBus™ specification. More
information is provided by these registers and they are either
accessed rapidly, at once, using the ‘multi parameter’ read
back scheme of this document, or in batches of two STATUS
and two ALARM registers.
Status_summary (0xD0) : This ‘manufacturer specific’
command is the basic read back returning STATUS and ALARM
register data, output voltage, output current, and internal
temperature data in a single read. Internal temperature
should return the temperature that is closest to a shutdown
level.

function is to provide visual identification of the power supply
being talked to and also to visually verify that the LEDs
operate and driven properly by the micro controller.
LEDS test OFF: Will turn-OFF simultaneously the four front
panel LEDs of the power supply.
Service LED ON: Requests the power supply to flash-ON the
Service (ok-to-remove) LED. The flash sequence is
approximately 0.5 seconds ON and 0.5 seconds OFF.
Service LED OFF: Requests the power supply to turn OFF the
Service (ok-to-remove) LED.
OR’ing Test: This command verifies functioning of output
OR’ing. At least two paralleled power supplies are required.
The host should verify that N+1 redundancy is established. If
N+1 redundancy is not established the test can fail. Only one
power supply should be tested at a time.
Verifying test completion should be delayed for approximately
30 seconds to allow the power supply sufficient time to
properly execute the test.
Failure of the isolation test is not considered a power supply
FAULT because the N+1 redundancy requirement cannot be
verified. The user must determine whether a true isolation
fault indeed exists.
To restart after a latch off either of five restart mechanisms
are available.
1. The hardware pin ON/OFF may be cycled OFF and
then ON.
2. The unit may be commanded to restart via I2C
through the Operation command by cycling the
output OFF followed by ON.
3. Remove and reinsert the unit.
4. Turn OFF and then turn ON AC power to the unit.
5. Changing firmware from latch off to restart.
Each of these commands must keep the power supply in the
OFF state for at least 2 seconds, with the exception of
changing to restart.
A successful restart shall clear all alarm registers, set the
restarted successful bit of the Status_2 register.
A power system that is comprised of a number of power
supplies could have difficulty restarting after a shutdown
event because of the non-synchronized behavior of the
individual power supplies. Implementing the latch-off
mechanism permits a synchronized restart that guarantees
the simultaneous restart of the entire system.
A synchronous restart can be implemented by;
1. Issuing a GLOBAL OFF and then ON command to all power
supplies,
2 . Toggling Off and then ON the ON/OFF (ENABLE) signal
3. Removing and reapplying input commercial power to the
entire system.
General performance descriptions
Default state: Power supplies are programmed in the default
state to automatically restart after a shutdown has occurred.
The default state can be reconfigured by changing non-volatile
memory (Store_user_code).
Delayed overcurrent shutdown during startup: Power
supplies are programmed to stay in a constant current state
for up to 20 seconds during power up. This delay has been
introduced to permit the orderly application of input power to
a subset of paralleled front-ends during power up. If the
overload persists beyond the 20 second delay, the front-end
will revert back into its programmed state of overload
protection.
Unit in Power Limit or in Current Limit: When output voltage
is > 36VDC the Output LED will continue blinking.
When output voltage is < 36VDC, if the unit is in the RESTART
mode, it goes into hiccup. When the unit is ON the output LED
is ON, when the unit is OFF the output LED is OFF.
When the unit is in latched shutdown the output LED is OFF.
Restart after a latchoff: PMBus™ fault_response commands
can be configured to direct the power supply to remain
latched off for over_voltage, over_temperature and
over_current.
August 14, 2018
The power supplies should be turned OFF for at least 20 – 30
seconds in order to discharge all internal bias supplies and
reset the soft start circuitry of the individual power supplies.
Auto_restart: Auto-restart is the default configuration for
over-current and over-temperature shutdowns. These
features are configured by the PMBus™ fault_response
commands
An overvoltage shutdown is followed by three attempted
restarts, each restart delayed 1 second, within a 1 minute
window. If within the 1 minute window three attempted
restarts failed, the unit will latch OFF. If within the 1 minute
less than 3 shutdowns occurred then the count for latch OFF
resets and the 1 minute window starts all over again
Dual Master Control:
Two independent I2C lines and Alert# signals provide true
communications redundancy allowing two independent
controllers to sequentially control the power supply.
A short or an open connection in one of the I2C lines does not
affect communications capability on the other I2C line. Failure
of a ‘master’ controller does not affect the power supplies and
the second ‘master’ can take over control at any time when
the bus is idle.

If the SMBAlert signal was actually triggered by the power
supply and not the I2C selector selector section of the µC, then
only the ‘master’ in control can clear the power supply
registers. Incomplete transmissions should not occur on either
bus.
Conceptual representation of the dual I2C bus system.
The Alert# line exciting the power supply combines the
Alert# functions of power supply control and
dual_bus_control.
Status_bus (0xD7): Bus_Status is a single byte read back.
The command can be executed by either master at any
time independent of who has control.

Test Function (0xDF)
Actual transfer is controlled by the I2C selector section of the
µC. A bus transfer only occurs during an idle state when the
‘master’ currently in control (in the execution process of a
control command) has released the bus by issuing a STOP
command. Control can be transferred at any time if the
‘master’ being released is executing a read instruction that
does not affect the transfer of command control. Note; The
µC can handle read instructions from both busses
simultaneously.
The command follows PMBus™ standards and it is not
executed until the trailing PEC is validated.
Status Notifications: Once control is transferred both
SMBAlert lines should get asserted by the I2C selector section
of the µC. The released ‘master’ is notified that a STATUS
change occurred and he is no longer in control. The
connected ‘master’ is notified that he is in control and he can
issue commands to the power supply. Each master must issue
a clear_faults command to clear his SMBAlert signal.

supply will revert back into its programmed state of overload

An overvoltage shutdown is followed by three attempted
restarts, each restart delayed 1 second, within a 1 minute
window. If within the 1 minute window three attempted
restarts failed, the unit will latch OFF. If within the 1 minute
less than 3 shutdowns occurred then the count for latch OFF
resets and the 1 minute window starts all over again
Unit in Power Limit or in Current Limit: When output voltage
is > 36VDC the Output LED will continue blinking.
When output voltage is < 36VDC, if the unit is in the RESTART
mode, it goes into hiccup. When the unit is ON the output LED
is ON, when the unit is OFF the output LED is OFF.
Certain transitionary states can occur before a final state is
reached. The STATUS and ALARM registers will not be frozen
into a notification state until the final state is reached. Once a
final state is reached the Alert# signal is set and the STATUS
and ALARM registers will not get reinstated until a clear_faults
is issued by the master. The only exception is that additional
state changes may be added to the original list if further
changes are noted.
When the unit is in latched shutdown the output LED is OFF.
Restart after a latchoff: PMBus™ fault_response commands
can be configured to direct the power supply to remain
latched off for over_voltage, over_temperature and
over_current.
To restart after a latch off either of five restart mechanisms
are available.
1. The hardware pin ON/OFF may be cycled OFF and
then ON.
2. The unit may be commanded to restart via I2C
through the Operation command by cycling the
output OFF followed by ON.
3. Remove and reinsert the unit.
4. Turn OFF and then turn ON AC power to the unit.
5. Changing firmware from latch off to restart.

Fault Management
All fault information is sticky. If the fault still persists after a
clear_faults has been issued, then the fault state will reassert.
All operational state information is not sticky.
The power supply differentiates between internal faults that
are within the power supply and external faults that the
power supply protects itself from, such as overload or input
voltage out of limits. The FAULT LED, FAULT PIN or i2c alarm is
not asserted for EXTERNAL FAULTS. Every attempt is made to
annunciate External Faults. Some of these annunciations can
be observed by looking at the input LEDs. These fault
categorizations are predictive in nature. Therefore, there is a
likelihood that a categorization may not have been made
correctly.

State Change Definition
•
A state_change is an indication that an event has occurred
that the MASTER should be aware of. The following events
shall trigger a state_change;
•
Initial power-up of the system when INPUT gets turned
ON . This is the indication from the power supply that it
has been turned ON. Note that the master needs to read
the status of each power supply to reset the
system_interrupt. If the power supply is back-biased
through the 8V_INT or the 5VSTB it will not issue an
SMBALERT# when INPUT power is turned back ON.
•
Whenever the power supply gets hot-plugged into a
working system. This is the indicator to the system
(MASTER) that a new power supply is on line.
•
Any changes in the bit patterns of the STATUS and
ALARM registers are a STATUS change which triggers the
SMBALERT# flag. Note that a host-issued command such
as CLEAR_FAULTS will not trigger an SMBALERT#
Hot plug procedures
Careful system control is recommended when hot plugging a
power supply into a live system. It takes about 15 seconds for
a power supply to configure its address on the bus based on
the analog voltage levels present on the backplane. If
communications are not stopped during this interval, multiple
power supplies may respond to specific instructions because
the address of the hot plugged power supply always defaults
to xxx0000 (depending on which device is being addressed
within the power supply) until the power supply configures its
address.
The recommended procedure for hot plug is the following:
The system controller should be told which power supply is to
be removed. The controller turns the service LED ON, thus
informing the installer that the identified power supply can be
removed from the system. The system controller should then
poll the module_present signal to verify when the power
supply is re-inserted. It should time out for 15 seconds after
this signal is verified. At the end of the time out all
communications can resume.
Hot plug configuration
During hot plug the power supply attempts to configure itself
to the bus voltage of a working system. The following are the
turn-ON steps implemented within the power supply:
•
Prior to turning ON the main output the power supply
reads the bus voltage present on the bus. If the bus
voltage and the commanded voltage (either default or
Vmargin) are the same, the power supply proceeds to
turn ON into its commanded value.
August 14, 2018
•
If the bus voltage and the commanded voltage do not
agree, the power supply ignores the commanded voltage
and waits for the external controller to command it to set
its output voltage. This step is required to ensure that
the plugged in power supply does not attempt to source
an entire system at an uncontrolled voltage level.
If the bus voltage is below 40Vdc the power supply
proceeds to turn ON into its commanded value.
Failure Predictions
Alarm warnings that do not cause a shutdown are indicators
of potential future failures of the power supply. For example,
if a thermal sensor failed, a warning is issued but an
immediate shutdown of the power supply is not warranted.
Another example of potential predictive failure mechanisms
can be derived from information such as fan speed when
multiple fans are used in the same power supply. If the speed
of the fans varies by more than 20% from each other, this is an
indication of an impending fan wear out.
The goal is to identify problems early before a protective
shutdown would occur that would take the power supply out
of service.
Information only alarms: The following alarms are for
information only, they do not cause a shutdown
•
Over temperature warning
•
Vout out-of-limits

•

LEDs
Three LEDs are located on the front faceplate. The AC_OK LED
provides visual indication of the INPUT signal function. When
the LED is ON GREEN the power supply input is within normal
design limits.
The second LED is the DC_OK LED. When GREEN the DC
output is present. When ‘blinking’ a power limit or overload
condition exists. When OFF the output is not present.
The third LED is the FAULT LED. A continuous RED condition
indicates that a fault exists and the power supply has been
shut down. Blinking of the RED LED in RS485 mode indicates
that communications with the controller was not established.
In I2C mode, blinking of the FAULT LED indicates an OTW.

independent µControllers. The boost (PFC) section is
controlled by the primary µController. The secondary DC-DC
converter is controlled by the secondary µController, and I2C
communications are being handled by the I2C Interface
µController.
Each of the µControllers contains a boot loader section and an
application section in memory. The purpose of the boot
loader section is to facilitate the upgrading capability
described here. All the commands for upgrading and memory
space required for incrementally changing the application
code are in this section. The application section contains the
running code of the power supply.
Contents of the upgrade are in a zip file

For some customers internal system re-programming is either
not feasible or not desired. These customers may obtain a reprogramming kit from GE Critical Power. This kit contains a
turn-key package with the re-program firmware.
Program.bin - The upgraded program contents are
located here. Each processor to be upgraded will
have its own file.
Unzipping the contents shows the following files

The system controller receives the upgrade package. It should
first check whether an upgrade is required followed by
upgrading those processors, one at a time, that are required
to be upgraded. Each processor upgrade needs to be validated
and once the upgrade is successfully completed the boot
loader within each processor will permit the application to run
after a reset. If the validation fails the boot loader will stay in
its section. The system controller can attempt another
upgrade session to see if it would complete successfully.
The Upgrade Package: This package contains the following
files;
•
Manifest.txt – The manifest describes the contents
of the upgrade package and any incidental
information that may be useful, for example, what
this upgrade contains or why is this upgrade
necessary
This file contains the version number and the
compatibility code of the upgraded program for
each of the three processors

After completion of the first data packet upload the Boot
loader increments the sequence number. A subsequent read
to the boot loader will return the incremented sequence
number and a STATUS byte. This is a validity check to ensure
that the sequence number is properly kept. The returned
STATUS byte is the same as the application status response. It
is appended here automatically to save the execution of
another command. It should be checked to ensure that no
errors are flagged by the boot loader during the download. If
an error occurred, terminate the download load and attempt
to reprogram again.

the power supply. Each record is stored into nonvolatile
memory at the time when a black box trigger event occurs.
Once five records are stored, additional records over-write the
oldest record.
The memory locations will be cleared, when the product is
shipped from the GE factory.
Operational use statistics
This feature of the black box includes information on the
repetition and duration of certain events in order to
understand the long-term operational state of the power
supply. The events are placed into defined buckets for further
analysis. For example; the power supply records how long
was the output current provided in certain load ranges.
Accessing the event records
The event records are accessed by uploading the entire
contents of the black box of the power supply into a folder
assigned by the user. Within the I2C protocol this upload is
accomplished by the upload_black_box (0xF0) command
described below. GE provides a Graphical User Interface
(GUI) that de-codes the contents of the black box into a set of
records that can be reviewed by the user.
Upload black box(0xF0): This command executes the upload
from the power supply to a file of the user’s choice.
The 100ms delay prior to the restart is mandatory to provide
enough time for the power supply to gather the required data
from the secondary DSP controller.

The data array supported by rev 1.3 of the GE Interface
Adapter is 32 x 64 comprising 2048 bytes of data.
The rolling event recorder
The purpose of the black box is to provide operational
statistics as well as fault retention for diagnostics following
either recoverable or non-recoverable fault events. Sufficient
memory exists to store up to 5 time-stamped snapshot
records (pages) that include the state of the status and alarm
registers and numerous internal measurement points within
