VAKPU VAKPU-side

chartOver/Under Voltage Relays provide protection to equipment where either an over or under voltage condition is potentially damaging. They are designed to operate when the operating voltage reaches a preset value and drop-out when the operating voltage drops to a level below the preset value.

The VAKPU Series can be used to monitor any 208-240V single phase voltage. The pick-up voltage setting is user-adjustable from 85-115% of the nominal voltage rating. The drop-out setting is adjustable from 80-95% of the pick-up setting. The relay energizes when the monitored voltage is above the pick-up setting longer than the adjustable pick-up time delay (T1) of 0.1-10 seconds. The relay de-energizes when the monitored voltage is below the drop-out setting for a period longer than the drop-out time delay (T2), which is an adjustable 0.1- 10 seconds.
