This feature monitors the output voltage, which is produced by the power supply itself. It is independent of a back-fed
voltage from a unit connected in parallel to the power supply output (e.g. redundant application).
Threshold voltage
typ.
21.4V (fixed)
Contact closes
As soon as the output voltage reaches 21.4V.
Contact opens
As soon as the output voltage falls below 21.4V.
