MODEL NUMBER
Parallel interface specifications.
All signals are referenced to ISO_GND unless otherwise indicated.
Isolated signal ground
(ISO_GND)
May be connected to any voltage in the range from +Vout+5VDC to -Vout-
5VDC.
Overtemperature
(OTW)
Output bi-level signal. Bi-level signals are open-collector (drain) with a 5mA
sink capability and maximum voltage stand-off of 60VDC.
Logic 0 : Signal precedes OT shutdown by 5ms.
Logic 1 : Normal operation.
Remote Inhibit
(INHIBIT)
Input bi-level signals. Bi-level input signals shall be no greater than 5VDC.
Logic 0 : Normal operation.
Logic 1 : Output inhibit.
Voltage margin down
(DOWN)
Input bi-level signals. Bi-level input signals shall be no greater than 5VDC.
Logic 0 : Nominal output voltage.
Logic 1 : 44.5 to 45.5VDC output.
Power good signal
(PWR_GOOD)
Output bi-level signal. Bi-level signals are open-collector (drain) with a 5mA
sink capability and maximum voltage stand-off of 60VDC.
Logic 0 : Output undervoltage.
Logic 1 : Output voltage normal.
Fault fail signal
(F/F ±)
Differential relay contact, isolated from all outputs and returns within the
power module.
Relay closed : Power supply failure
Relay open : Normal operation.
Power fail warning signal
(PFW)
Output bi-level signal. Bi-level signals are open-collector (drain) with a 5mA
sink capability and maximum voltage stand-off of 60VDC.
Logic 0 : Signal precedes loss of output power by 5ms.
Logic 1 : Normal operation.
Module Missing Pin
(MM)
Provision for detection of unseated or removed module. MM pins are
common internal to the power supply. Internal pull-up resistor to +5VDC logic
bias, referenced to RS-.
Auxiliary Output
(AUX ±)
12VDC auxiliary output. Isolated from both the main output and the isolated
signal ground. May be utilized for external housekeeping supply and
connected to either main output or isolated signal ground.
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 is open-collector (drain) with a
5mA 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.
Remote Enable
(ENABLE)
Input bi-level signal. Bi-level input signal shall be no greater than 5VDC.
Logic 0 : Output inhibited.
Logic 1 : Normal operation.
Reset
(RESET)
Input bi-level signal. Bi-level input signal shall be no greater than 5VDC.
Logic 0 : Resets fault indicators without unit shut-down.
Logic 1 : Normal operation.
AC Good
(AC OK)
Output bi-level signal. Bi-level output signal is open-collector (drain) with a
5mA sink capability and maximum voltage stand-off of 60VDC.
Logic 0 : AC input below normal operating range.
Logic 1 : AC input within steady-state operating range (170 to 264VAC).
Voltage monitoring
(VMARG)
Input analog signal referenced to RS-. Adjusts output up to 4VDC higher than
the nominal set point.

Protection
Thermal protection - automatic shut-off for fan failure or internal
overtemperature.
Output Overload and Short Circuit - automatic shut-down after 30 seconds.
Current regulated output down to less than 1VDC.
Output Overvoltage - automatic shut-down for both main (60VDC max.) and
auxiliary (15.6VDC max.) outputs.
Output Undervoltage - automatic shut-down below 42VDC.
Current Share
Active current sharing for up to 9 AFE2000 power modules.
Short Pin
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.
