Parallel interface specifications
Output bi-level signal. Bi-level output signal is open-collector (drain) with a
ꢀmA sink capability and maximum voltage stand-off of 60VDC.
Logic 0 : AC input below normal operating range.
All signals are referenced to ISO_GND unless otherwise indicated.
Logic 1 : AC input within steady-state operating range.
Isolated signal ground
(ISO_GND)
May be connected to any voltage in the range from +Vout+ꢀVDC to -Vout-
ꢀVDC.
Voltage monitoring
Input analog signal referenced to RS-. Adjusts output up to 4VDC higher than
the nominal set point.
(VMARG)
Overtemperature
(OTW)
Output bi-level signal. Bi-level signals with a ꢀmA sink capability and
maximum voltage stand-off of 60VDC.
Logic 0 : Signal precedes OT shutdown by ꢀms.
Logic 1 : Normal operation.
Features
Remote On/Off
(INHIBIT)
Input bi-level signals. Bi-level input signals shall be no greater than ꢀVDC.
Logic 0 : Output inhibit.
Live insertion and removal
OR-ing diodes provided on output.
Logic 1 : Normal operation.
Voltage monitoring jacks
Voltage margin down
(DOWN)
Located on front panel.
Input bi-level signals. Bi-level input signals shall be no greater than ꢀVDC.
Logic 0 : Nominal output voltage.

Power good signal
(PWR_GOOD)
Output bi-level signal. Bi-level signals are open-collector (drain) with a ꢀmA
sink capability and maximum voltage stand-off of 60VDC.
Logic 0 : Output undervoltage.
Protection
Thermal protection - automatic shut-off for fan failure or internal
overtemperature.
Logic 1 : Output voltage normal.
Fault fail signal
(F/F ±)
Output Overload and Short Circuit - automatic shut-down after ±0 seconds.
Current regulated output down to less than 1VDC.
Differential relay contact, isolated from all outputs and returns within the
power module.
Relay closed : Power supply failure
Relay open : Normal operation.
Output Overvoltage - automatic shut-down for both main (60VDC max.) and
auxiliary (1ꢀ.6VDC max.) outputs.
Power fail warning signal
(PFW)
Output Undervoltage - automatic shut-down below 42VDC.
Output bi-level signal. Bi-level signals are open-collector (drain) with a ꢀmA
sink capability and maximum voltage stand-off of 60VDC.
Logic 0 : Signal precedes loss of output power by ꢀms.
Logic 1 : Normal operation.
Current Share
Active current sharing for up to 9 AFE1200 power modules.
Module Missing Pin
(MM)
Short Pin
Provision for detection of unseated or removed module. MM pins are
common internal to the power supply. Internal pull-up resistor to +ꢀVDC logic
bias, referenced to isolated GND
Short pin located in the output connector initiates shut down of the power
supply output when the power supply is removed from the host power shelf.
Auxiliary Output
(AUX ±)
12VDC auxiliary output. Isolated from the main output. May be utilized for
external housekeeping supply and connected to either main output.
Current Monitor
(IMON)
Current source which mirrors magnitude of the output current. Signal return
is referenced to RS-.
Current Limit
(CL)
Output bi-level signal. Bi-level output signal with a ꢀmA sink capability and
maximum voltage stand-off of 60VDC.
Logic 0 : Output is in current mode control and is current limiting.
Logic 1 : Normal operation.
Reset
(RESET)
Input bi-level signal. Bi-level input signal shall be no greater than ꢀVDC.
Logic 0 : Normal operation.
Logic 1 : Resets fault indicators without unit shut-down.
International Safety Standard Approvals
