Operation
Voltage Monitor Relays provide protection to equipment where an over or under voltage condition is potentially damaging. They monitor either AC single phase (50-400Hz) or DC voltages. No supply (input) voltage is required.The pick-up voltage setting is user-adjustable from 85-115% of the nominal voltage rating. As standard, the drop-out voltage setting is fixed at 3% below the pick-up voltage setting. The relay is energized when the monitored voltage is above the pick-up setting. The relay de-energizes when the monitored voltage is below the drop-out setting.
