Over/Under Voltage Relays provide protection to equipment where 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 pick-up voltage setting is user-
adjustable from 85-115% of the
nominal voltage rating. As
standard, the VAP Series has a
drop-out voltage setting fixed at
95% of the pick-up voltage setting.
An adjustable drop-out setting of
75-95% of the pick-up setting is
available on the VAKP Series. The
relay energizes when the moni-
tored voltage is above the pick-up
setting. The relay de-energizes when the monitored voltage is below the drop-out setting
for a period longer than the drop-out time delay (T), which is adjustable from 0.5-10
seconds for VA Series products. A time delay on drop-out fixed at 500ms is available
(see Page 28).
