OVER/UNDER VOLTAGE | FIXED TIME DELAY ON DROP-OUT

12-120V | VM Series

Over/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 pick-up voltage setting is
user-adjustable from 85-115%
of the nominal voltage rating.
As standard, the VMP 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 VMKP 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 a fi xed 500ms for VM Series products. If an adjustable
time delay on drop-out is required, see VAP/VAKP Series.
