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
fi xed 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
monitored 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 dropout time delay (t), which is adjustable from 0.5-10 seconds for VA Series products.
