The CAR0812FP series of rectifiers provide highly efficient isolated power from world-wide commercial AC mains.
Offered in the industry standard compact 1U form factor, these rectifiers complement the CAR0812DC converter line,
providing comprehensive solutions for systems connected either to commercial ac mains or 48/60VDC power plants.
This plug and play approach, between AC and DC input units, has significant advantages since systems can be readily
reconfigured by simply replacing the power supply.
The high-density, front-to-back airflow is designed for minimal space utilization and is highly expandable for future
growthThe industry standard PMBus compliant I2C communications buss offers a full range of control and monitoring
capabilities. The SMBAlert signal pin alerts customers automatically of any state change within the power supply.

Data Sheet
CAR0812FP series rectifier
Input: 85VAC to 264VAC; Output: 12VDC @ 850W; 3.3VDC or 5 VDC @ 1A
Control and Status
Status signals
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 the signal
pin (Vprog) and the PMBus command, (Vout_command) .
Output current monitor (Imon): A voltage level proportional
to the delivered output current is present on this pin. The
signal level is 0.04V per amp ± 0.25V.
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 12VDC and the unit
output voltage can be controlled via the PMBus command,
(Vout_command).
Analog controls: Details of analog controls are provided in
this data sheet under Signal Definitions.
Common ground: All signals and outputs are referenced to
Output return. These include ‘Vstb return’ and ‘Signal return’.
Control Signals
Voltage programming (Vprog): An analog voltage on this
signal can vary the output voltage ± 10% of nominal, from
10.8VDC to 13.2VDC. The equation of this signal is:
VOUT = 10.8 + (Vprog * 0.96) where Vprog = 0 to 2.5VDC
Between 2.5 and 3V the output stays at 13.2VDC. If Vprog is >
3V, or left open, the programming signal is ignored and the
unit output is set at the setpoint of 12VDC.
Load share (Ishare): This is a single wire analog signal that
is generated and acted upon automatically by power
supplies connected in parallel. The Ishare pins should be tied
together for power supplies if active current share among
the power supplies is desired. No resistors or capacitors
should get connected to this pin.
Remote_ON/OFF: Controls presence of the 12V DC output
voltage. This is an open collector, TTL level control signal
that needs to be pulled HI externally through a resistor.
Input_OK: A TTL compatible status signal representing
whether the input voltage is within the anticipated range.
This signal needs to be pulled HI externally through a
resistor.
DC_OK: A TTL compatible status signal representing
whether the output voltage is present. This signal needs to
be pulled HI externally through a resistor.
Over_temp_warning: A TTL compatible status signal
representing whether an over temperature exists. This signal
needs to be pulled HI externally through a resistor.
If an over temperature should occur, this signal would pull
LO for approximately 10 seconds prior to shutting down the
power supply. The unit would restart if internal temperatures
recover within normal operational levels. At that time the
signal reverts back to its open collector (HI) state.
Fault: A TTL compatible status signal representing whether
a Fault occurred. This signal needs to be pulled HI externally
through a resistor.
This signal activates for OTP, OVP, OCP, INPUT fault or No
output.
PS_Present: This pin is connected to ‘output return’ within
the power supply. Its intent is to indicate to the system that
a power supply is present. This signal may need to be pulled
HI externally through a resistor.
Interrupt (SMBAlert): A TTL compatible status signal,
representing the SMBusAlert# feature of the PMBus
compatible i2C protocol in the power supply. This signal
needs to be pulled HI externally through a resistor.
Serial Bus Communications
A turn OFF command either through this signal (Remote
ON/OFF) or firmware commanded would turn OFF the 12V
output.
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.
Enable: This is a short signal pin that controls the presence
of the 12Vdc main output. This pin should be connected to
‘output return’ on the system side of the output connector.
The purpose of this pin is to ensure that the output turns ON
after engagement of the power blades and turns OFF prior
to disengagement of the power blades.
All signals are referenced to ‘Signal Return’.
Write protect (WP): This signal protects the contents of the
EEPROM from accidental over writing. When left open the
EEPROM is write protected. A LO (TTL compatible) permits
writing to the EEPROM. This signal is pulled HI internally by
the power supply.
Fan speed control: The speed of the fan can be increased
above that point that is required for internal cooling. The
speed of the fan cannot be decreased below internal
cooling requirements.
Device addressing: The microcontroller (MCU) and the
EEPROM have the following addresses:

Address lines (A2, A1, A0): These signal pins allow up to eight
(8) modules to be addressed on a single I²C bus. The pins are
pulled HI internal to the power supply. For a logic LO these
pins should be connected to ‘Output Return’
Serial Clock (SCL): The clock pulses on this line are generated
by the host that initiates communications across the I²C
Serial bus. This signal requires an external pull-up to 3.3V.
Serial Data (SDA): This line is a bi-directional data line. This
signal requires an external pull-up to 3.3V.

CAR0812FP series rectifier
Input: 85VAC to 264VAC; Output: 12VDC @ 850W; 3.3VDC or 5 VDC @ 1A
Digital Feature Descriptions
PMBus™ compliance: The power supply is fully compliant
to the Power Management Bus (PMBus™) rev1.2
requirements.
Manufacturer specific commands located between
addresses 0xD0 to 0xEF provide instructions that either do
not exist in the general PMBus specification or make the
communication interface simpler and more efficient.
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.
preceding read instructions. The PEC is appended to the
message by the device that supplied the last byte.
SMBAlert#: The µC driven SMBAlert# 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 either receives a ‘clear’ instruction as outlined below
or executes a READ STATUS_WORD. If the alarm state is still
present after the STATUS registers were reset, then the
signal will revert back into its LO state again and will latch
until a subsequent reset signal is received from the host
controller.
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
The power supply will clear the SMBusAlert# signal (release
the signal to its HI state) upon the following events:
•
•
•
•
Clock
Figure 1. Example waveforms showing clock
stretching.
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. The minimum clock speed specified by
SMBus is 10 kHz.
Packet Error Checking (PEC): Although the power supply will
respond to commands with or without the trailing PEC, it is
highly recommended that PEC be used in all
communications. 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 should require validation to ensure
that the correct command is executed.
Receiving a CLEAR_FAULTS command
The main output recycled (turned OFF and then ON) via
the ENABLE signal pin
The main output recycled (turned OFF and then ON) by
the OPERATION command
Execution of a READ of the STATUS_WORD register
Global broadcast: This is a powerful command because it
can instruct all power supplies to respond simultaneously in
one command. But it does have a serious disadvantage.
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.
Read back delay: The power supply needs at least 2
seconds to configure the status registers into their final
state. For example, a 2 second delay is required prior to
reading back status information after a clear_faults has
been issued to clear the status registers.
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.
PEC is a CRC-8 error-checking byte, based on the polynomial
C(x) = x8 + x2 + x + 1, in compliance with PMBus™

Command Descriptions
Operation (01) : By default the Power supply is turned ON at
power up as long as Power ON/OFF signal pin is active HI.
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
Unit ON
Unit OFF
DATA BYTE
80
00
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.
Clear_faults (03): This command clears all STATUS and
FAULT registers and resets the SMBAlert# line.
If a fault still persists after the issuance of the clear_faults
command the specific registers indicating the fault are reset
and the SMBAlert# line is activated again.
WRITE_PROTECT register (10): Used to control writing to the
PMBus device. The intent of this command is to provide
protection against accidental changes. All supported
command parameters may have their parameters read,
regardless of the write_protect settings. The contents of this
register can be stored to non-volatile memory using the
Store_default_code command. The default setting of this
register is disable_all_writes except write_protect 0x80h.

DATA BYTE

Vout_Command (21) : This command is used to change the
output voltage of the power supply. Changing the output
voltage should be performed simultaneously to all power
supplies operating in parallel using the Global Address
(Broadcast) feature. If only a single power supply is
instructed to change its output, it may attempt to source all
Sept.3, 2021
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.
Vout_OV_warn_limit (42): OV_warning is extremely useful
because it gives the system controller a heads up that the
output voltage is drifting out of regulation and the power
supply is close to shutting down. Pre-amative action may
be taken before the power supply would shut down and
potentially disable the system.
OC and OT_fault_ response (47, 50): The default response
for both OC and OT is auto_restart (hiccup). Each register,
individually, can be reconfigured into a latched state.
Latched and hiccup are the only supported states.
Restart after a latch off: Either of four restart possibilities
are available. The hardware pin Remote ON/OFF may be
turned 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. The fifth way is by
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 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 Remote ON/OFF signal
3. Removing and reapplying input commercial power to the
entire system.
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
recovering from over-current and over-temperature
shutdowns.
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 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.

Vin_UV_warn_limit (58): This is another warning flag
indicating that the input voltage is decreasing dangerously
close to the low input voltage shutdown level.
Status_word (79): returns two bytes of information. The
upper byte bit functionality is tabulated in the Status_word
section. The lower byte bit functionality is identical to
Status_byte.
Fan_speed (D7): This register can be used to ‘read’ the fan
speed in adjustment percent (0 – 100%) or set the fan speed
in adjustment percent (0 – 100%). The speed of the fan
cannot be reduced below what the power supply requires
for its operation. The register value is the percent number, it
is not in linear format.
Invalid commands or data: The power supply notifies the
MASTER if a non-supported command has been sent or
invalid data has been received. Notification is implemented
by setting the appropriate STATUS and ALARM registers and
setting the SMBAlert# flag.
Control and Read accuracy:
The estimates below are believed to be reasonable under
most operating conditions. However, these are typical
numbers and not hard bound values that cannot be
exceeded. In most nominal operating conditions the
returned values are significantly better than these
estimates.
Note that temperature measurements are accurate around
the shutdown limits and they get increasingly less accurate
as the temperature level decreases.

EEPROM
The microcontroller has 96 bytes of EEPROM memory
available for the system host.
Another separate EEPROM IC will provide another 128 bytes
of memory with write protect feature. Minimum information
to be included in this separate EEPROM: model number,
revision, date code, serial number etc.
LEDs
Two 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 DC/FLT is a tri-state LED. When GREEN there are no
faults and DC output is present. When AMBER a fault condition
exists but the power supply still provides output power. When RED
then a fault condition exists and the power supply does not provide
output power.
