GE
CAR2012TE series rectifier
Input: 85Vac to 264Vac; Output: 12 Vdc @ 2000W; 3.3Vdc or 5 Vdc @ 4A
Read_input_string (0xD4): Reads back the input voltage and
input power consumed by the power supply.
Read_Alarm_state (0xD2): This command returns the two
ALARM register values using the standard ‘read’ format.

Read_mfr_rev [0xD5]: A total of 4 bytes are returned. Each
byte is partitioned into high and low nibbles.
Example: FF is read as 16.16
Power Delivery: The power supply compares its internal
sourced current to the current requested by the current share
pin. If the difference is > 10A, a fault is issued.
11 is read as 1.1

Over temperature warning: This flag is set approximately
5C prior to the commencement of an over temperature
shutdown.
For example; the read returns one byte for each device (i.e. 0
x 10102114 ). The sequence is series, hardware rev, DSP, and
I2C micro. 0x10 in the first byte indicates series 1.0. The
second number indicates that the hardware rev is 1.0. The
third number 21 for the DSP indicates revision 2.1, and the
number 14 for the i2c micro indicates revision 1.4.
Read_Fan_speed (0xD3) : Returns the commanded speed in
percent and the measured speed in RPM. Up to 3 fans are
supported. If a fan does not exist, or if the command is not
supported the unit return 0x00.
Read_run_timer (0xD6): This command reads back the
recorded operational ON state of the power supply in hours.
The operational ON state is accumulated from the time the
power supply is initially programmed at the factory. The
power supply is in the operational ON state both when in
standby and when it delivers main output power.
