Preliminary Data Sheet
GE
CAR2512TE Front-End
Input: 90VAC to 264VAC; Output: 12 VDC @ 2500W; 3.3/5VDC standby @ 15W
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.
13KZ51018193xxx, is decoded as;
13 – year of manufacture, 2013
KZ – manufacturing location, in this case Matamoros
51 – week of manufacture
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. 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.
018193xxx – serial #, mfr choice
note: if the additional xxx space is not utilized then F’s are
filled in, (i.e. 018193FFF), ensuring that the actual serial
number is clearly identified.
Read_mfr_rev (D5): Total 4 bytes
Each byte is partitioned into high and low nibbles.
Example: FF is read as 16.16
11 is read as 1.1
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;
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.
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
EEPROM
The microcontroller has 96 bytes of EEPROM memory available
for the system host.
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.
LEDs
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.
Two LEDs are located on the front faceplate. The INPUT OK LED
provides INPUT signaling function. When the LED is ON GREEN
the power supply input is within normal design limits.
Mfr_ID (99): Manufacturer in ASCII – 5 characters maximum,
General Electric – Critical Power represented as,
GE-CP
The second LED DC/FLT indicates three states. 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.
Mfr_Model (9A): Total 16 bytes: CAR2512TEXXXZ01
Mfr_serial (9E): Product serial number includes the
manufacturing date, manufacturing location in up to 15
characters. For example:
February 7, 2014
