Power Supply Module LED Indicators
There is a single bi-color LED to indicate power supply status. When AC is applied to the PSU
and standby voltages are available the LED blinks green. The LED turns on solid green to
indicate that all the power outputs are available. In case of OCP or OVP or OTP or fan failure or
under voltage the LED should turn ON solid amber. Refer to the following table for conditions of
the LEDs.

Blink Green
Power supply DC outputs ON and OK
Green
Power supply shutdown due to over current, over temperature, fan failure,
over voltage, or under voltage.
Amber
Power supply failed and AC fuse open or other critical failure.

AC Input Voltage Specification
The power supply will operate within all specified limits over the following input voltage ranges.
Harmonic distortion of up to 10% THD will not cause the power supply to go out of specified
limits. The power supply shall power off if the AC input is less than 70 VAC. The power supply
shall operate properly at 85 VAC input voltage to guarantee proper design margins.

1
Maximum input current at low input voltage range shall be measured at the lowest input voltage which the power supply
continues to operate (70 VAC
≤
Vin < 85 VAC).
2
Maximum input current at high input voltage range shall be measured at 180 VAC.
3
This is not intended to be used for determining agency input current markings.
Maximum rated input current is measured at 100 VAC and 200 VAC
.
