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.

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.

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

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
