These rectifiers are ideal for either datacom or telecom applications such as enterprise networking, remote base
stations, mid to high-end servers, and storage equipment, where mid to light load efficiency is of key importance
given the nature of the power consumption of the end application.
The high-density, front-to-back airflow is designed for minimal space utilization and is highly expandable for future
growth. The industry standard PMBus compliant I
2
C 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.

Status and Control
Some functions have two means of monitor/control; A
signal level that represents the analog value being
measured or controlled, or, reading/writing via the i
2
C
port the measured value or the control command.
Unless otherwise noted, control via the signals pins is
‘active’ so long that a firmware based command is not
initiated. Once firmware initiates a command that is also
represented on a signal pin, the firmware takes over and
replaces the hardware based control signal. Firmware
control is maintained until bias power to the processor is
interrupted. Once bias power is removed the processor
resets and the analog signal pin control is ‘active’ until
firmware takes over control.
Details of analog controls are provided in this data sheet
under Signal Definitions. GE Energy will provide separate
application notes on the I2C protocol. Contact your local
GE Energy representative for details.
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 the presence of the main
24Vdc output voltage. This is an open collector, TTL level
control signal. This signal needs to be pulled HI
externally through a resistor. Maximum collector voltage
is 12Vdc and the maximum sink current is 1mA. A Logic
1 (TTL HI level) turns ON the 24Vdc output, while a Logic
0 (TTL LO level) turns OFF the 24Vdc output.
A turn OFF command either through this signal (Remote
ON/OFF) or firmware commanded would turn OFF the
24V output.
Enable:
This is a short signal pin that controls the
presence of the 24Vdc 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.
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.
Signal Definitions
All signals and outputs are referenced to Output return.
These include ‘Vstb return’ and ‘Signal return’.
Input Signals
Voltage programming (V
prog
):
An analog voltage on this
signal can vary the output voltage ± 10% from 21Vdc to
29Vdc. The equation of this signal is:
V
out
= 21 + (V
prog
* 3.2) 0 < V
prog
< 2.5
If 2.5 < Vprog < 3, the output is 29V. If Vprog is > 3V or
left open the programming signal is ignored and the unit
output is set at the setpoint of 24Vdc.
Output signals
Output current monitor (Imon):
A voltage level of
0.1V/Amp proportional to the delivered output current is
present on this pin. Accuracy: ± 500mV for loads > 25%
FL.

CAR2024FP series rectifier
Input: 90Vac to 264Vac; Output: 24Vdc @ 83A; 3.3Vdc or 5 Vdc @ 1A
AC 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. Maximum sink current
≤
4mA and the max
voltage is 12Vdc. Open collector (HI) on this signal
indicates that the input voltage is applied within the
specified input range.
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. Maximum
sink current
≤
4mA and the max voltage is 12Vdc. Open
collector (HI) on this signal indicates that the output
voltage is present.
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.
Maximum sink current
≤
4mA and the max voltage is
12Vdc. Open collector (HI) on this signal indicates that
temperatures are normal.
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. Maximum sink current
≤
4mA and the max voltage is 12Vdc. Open collector (HI)
on this signal indicates that no Fault is present.
This signal activates for OTP, OVP, OCP, AC 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
2
compatible i C protocol in the power supply. This signal
needs to be pulled HI externally through a resistor.
Maximum sink current
≤
4mA and the pull up resistor
should be tied to 3.3Vdc. Open collector (HI) on this
signal indicates that no Interrupt has been triggered.
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 is pulled up
internally to 3.3V by a 10kΩ resistor. The end user
should add additional pull up resistance as necessary to
ensure that rise and fall time timing and the maximum
sink current is in compliance to the I²C specifications.
Serial Data (SDA):
This line is a bi-directional data line. .
This signal is pulled up internally to 3.3V by a 10kΩ
resistor. The end user should add additional pull up
resistance as necessary to ensure that rise and fall time
timing and the maximum sink current is in compliance to
the I²C specifications.
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.
See the communications protocol for further information.
