Status and Control
Some features, such as programming of the output voltage,
may be controlled both by hardware and firmware.
Unless otherwise noted, control of the output voltage via the
signal pin (Vprog) is ‘active’ and overrides as long as the
signal voltage is ≤ 3Vdc. A firmware initiated command,
attempting to change the output voltage will be ignored as
long as the signal voltage (Vprog) is ≤ 3Vdc
Details of analog controls are provided in this data sheet
under Signal Definitions. GE Energy will provide separate
application notes for the I2C protocol ( Document
#97FS2855). Contact your local GE Energy sales
representative for details.
Note that most control and capability functions
Signal Definitions
All signals and outputs are referenced to Output return.
These include ‘Vstb return’ and ‘Signal return’.
Input Signals
Note: Refer to the individual rectifier data sheets for
supported features.
Voltage programming (Vprog): An analog voltage on this
signal can vary the output voltage of all modules.
If 12V output CAR1812 or CAR1612 rectifiers are used, the
output can vary ± 10% from 10.8Vdc to 13.2Vdc. The
equation of this signal is:
Vout = 10.8 + (Vprog * 0.96) 0 < Vprog < 2.5
If 2.5 < Vprog < 3, the output is 13.2V. If Vprog is > 3V or left
open the programming signal is ignored and the unit output
is set at the setpoint of 12Vdc.
This signal is paralleled among the power supplies.
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 are tied together
among the power supplies in the shelf. No resistors or
capacitors should get connected to this pin.
Remote ON/OFF: Controls the presence of the main 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 main output, while a Logic 0 (TTL LO level) turns OFF
the main 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.
These signals are brought out independently for each power
supply.
Enable (ON/OFF): This is a short signal pin that controls the
presence of the 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.
These signals are brought out independently for each power
supply.
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. Note: only for factory programming.
This signal is interconnected among the power supplies
Output signals
Output current monitor (Imon): A voltage level proportional
to the delivered output current is present on this pin. The
signal level is 150A = 3V when the CAR182 or CAR1612
rectifiers are used.
These signals are brought out independently for each power
supply.
INPUT 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.
These signals are brought out independently for each power
supply.
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.
These signals are brought out independently for each power
supply.
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.
These signals are brought out independently for each power
supply.
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.
These signals are brought out independently for each power
supply.
This signal activates for OTP, OVP, OCP, AC fault or No
output.
Module 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.
