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
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.

C
Signal Definitions
All signals and outputs are referenced to Output return.
These include ‘Vstb return’ and ‘Signal return’.
Input Signals
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 4mA. A Logic
1 (TTL HI level) turns ON the 12Vdc output, while a Logic
0 (TTL LO level) turns OFF the 12Vdc output.
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.
Output signals
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.

CAR1812FP series dc-dc converter
Input: 85Vac to 264Vac; Output: 12 Vdc @ 1800W; 3.3Vdc or 5 Vdc @ 1A
DC OK: A TTL compatible status signal representing
whether the output voltage is present. This signal is
internally pulled HI to 3.3V via a 10kΩ resistor. Maximum
sink current ≤ 4mA and the max voltage is 12Vdc. Open
collector (HI) on this signal indicates that the output
voltage is present.
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.
SMBAlert: A TTL compatible status signal, representing
the SMBusAlert# feature of the PMBus compatible i
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.

C
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’.
Device addressing: The microcontroller (MCU) and the
EEPROM have the following addresses:
Device Address Address Bit Assignments
MCU 0xBx 1 0 1 1 A2 A1 A0 R/W
EEPROM 0xAx 1 0 1 0 A2 A1 A0 R/W
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’
(Most to Least Significant)
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.
Communications Protocol
The I²C protocol is described in detail by the I2C and
PMBus Serial Communications Protocol for the CAR
Family of Power Supplies application note.
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 provides visual indication of
three different states of the power supply. When the LED
is GREEN then there are no faults and the DC output is
present. When the LED is AMBER then a fault condition
exists but the power supply still provides output power.
When the LED is RED then a fault condition exists and
the power supply does not provide output power.
