Operation

Nominal Voltage Monitor

The SVM monitors single phase AC or DC voltages and operates a set of dry contacts. Several voltage ranges are available. The control is set to the nominal voltage and the relay will drop out when the percentage over or under voltage condition is reached. The LED lights when conditions are normal and the output relay is energized. A time delay controls the effects of short term voltage variations. Fixed delay is 0.5 second.
