CP2725AC48TEZ-FB Rectifier
Input: 100-120/220-240 Vac; Output: 2725W1 @ 52Vdc; 5 Vdc @ 4W
Status and Control
The Rectifier provides three means for monitor/control: analog
RS485or I2C.
Details of analog controls are provided in this Technical
Requirements under Signal Definitions. GE Energy will provide
separate application notes on the RS485 and I2C protocol for
users to interface to the CPL RECTIFIERs. Contact your local GE
Energy representative for details.
Hot Plug
The Rectifier is designed to accommodate rapid extraction and
reinsertion into either RS485 or I2C based protocol
configurations as set by the protocol pin. The protocol state of
the Rectifier shall reset immediately after disengagement from
the mating connector and the Rectifier will configure itself to
the state set by the protocol pin upon reinsertion.
Control Definitions
All signals are referenced to Logic_GRD unless otherwise noted.
See the Signal Definitions Table at the end of this document for
further description of all the signals.
Input Signals
Margining: Set point of the Rectifier can be changed via this
input pin. Programming can be either a voltage source or a
resistance divider. The margining pin is connected to 3.3Vdc via
a 10kΩ resistor inside the Rectifier. See graphs below.
Module Present Signal: This signal has dual functionality. It can be
used to alert the system when a module is inserted. A 500Ω resistor
is present in series between this signal and Logic_GRD. An external
pull-up should not raise the voltage on the pin above 0.25Vdc.
Above 1Vdc, the write_protect feature of the EEPROM is enabled.
Protocol Select: Establishes the communications mode of the
rectifier, between analog/I2C and RS485 modes. For RS485, connect
10kΩ pull-down resistor to 54_OUT(-DC).
Enable: On/Off control when I2C communications are utilized as
configured by the Protocol pin. This pin must be pulled low to turn
ON the rectifier. The rectifier will turn OFF if either the Enable or the
ON/OFF pin is released. This signal is referenced to Logic_GRD. This
function is not supported in RS485 mode.
ON/OFF: This is a short pin utilized for hot-plug applications to
ensure that the rectifier turns OFF before the power pins are
disengaged. It also ensures that the rectifier turns ON only after the
power pins have been engaged. Must be connected to V_OUT (-DC).
Output Signals
Power Capacity: A HI on this pin indicates that the rectifier delivers
high line rated output power; a LO indicates that the rectifier is
connected to low line configured for 1200W operation.
Power Fail Warning: This signal is HI when the main output is being
delivered and goes LO for the duration listed in this data sheet prior
to the output decaying below the voltage level listed in this data
sheet.

RS485 mode default: When the unit is powered ON in RS-485 mode
the default operational state is powered ON. An RS-485 mode unit
shall go to remote standby for any of the following conditions:
Interlock Open, or loss of AC.
RS485 mode rise time: When the unit is powered ON in RS485 mode
the rise time defaults to load current walk-in. The rise time can be
configured to be rapid turn-ON independent of the load profile.

An open circuit on this pin reverts the voltage level back to the
original setting of 48V
Software commanded margining overrides the hardware set
point indefinitely or until the default setting is reinstated for
example if input power and bias power have been removed
from the module.
January 7, 2013
Fault: This signal goes LO for any failure that requires Rectifier
replacement. Some of these faults may be due to:
Fan Speed Control: The fan speed can be instructed to turn faster
than what is required by the power supply using either the RS485 or
I2C protocols. The RS485 command for this feature is:
