Description
The CAR1212FP 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 CAR1212DC 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
growth.

Status and 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.
This signal is not overwritten by the firmware ON/OFF
instruction. The default firmware setting is ON. An OFF
command either through this signal or firmware would turn
OFF the power supply.
The default state re-initializes if bias power is interrupted to
the processor.
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.
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. Used only for factory programming
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 ± 5% from 11.4Vdc to
12.6Vdc. The equation of this signal is:
V
out
= 11.4 + (V
prog
* 0.3) 0 < V
prog
< 4
If Vprog is > 4V 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 the presence of the main 12Vdc
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 20mA. A Logic 1 (TTL HI level)
turns ON the 12Vdc output, while a Logic 0 (TTL LO level)
turns OFF the 12Vdc output.
Output signals
Output current monitor (Imon):
A voltage level of 0.05V / A
proportional to the delivered output current is present on
this pin. Accuracy ±10% of FL at loads > 25% of FL.
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
≤
20mA 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
≤
20mA 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
≤
20mA 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
compatible i
2
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.
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 not pulled up internally. The end
user should add pull up resistance to 5Vdc 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 not pulled up internally . The end user should add
pull up resistance to 5Vdc as necessary to ensure that rise
and fall time timing and the maximum sink current is in
compliance to the I²C specifications.

The CAR1212FPx without extended i2c communications

Bits 0, 1, 3, and 5 are ‘read_only’ and are HI [1] during normal
operation. The rectifier needs to be biased externally in order to
‘read’ its operational state without the presence of input power.
Bit 4 is a ‘read/write’ bit that can be used to verify the ON/OFF
commanded state or change the commanded output of the
rectifier. In order to turn the output OFF this bit needs to be pulled
LO [0].
No PEC support is provided. Standard i

c commands apply.
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 ‘Signal Return’.
