Auxiliary Signals
Open collector logic signal goes and stays HIGH
100mS to 500mS after main output reaches
regulation.
Goes LOW with 5mS warning before loss of
DC output after loss of AC power.
AC Power Fail:
DC OK:
Fan Output:
Connect to inhibit pin (J201 pin 5) to output
common to inhibit the DC output.
12V @ 1A
Inhibit:
Compensates for up to 250mV drop in load
lines.
Forced Current Sharing provided for up to 5
units connected in parallel.
