12-480V | VWKP Series
Voltage Band Relays provide protection to equipment that is required to operate
within an upper and lower voltage limit. As long as the operating voltage remains
within an Over and Under Voltage range, the internal relay stays energized. If the
operating voltage falls outside this range, the relay will drop-out.

table below. The under voltage setting (Umin) is adjustable from 75-95% of the over
voltage setting (Umax). The relay energizes (and the LED is Red) when the monitored
voltage is between the over and under voltage settings. The relay de-energizes (and
the LED is Green) when the monitored voltage falls outside the over or under voltage
settings for a period longer than the drop-out time delay (t), which is adjustable from
0.1-10 seconds. The relay re-energizes when the monitored voltage returns to a
value between the over and under voltage settings for a period longer than the
pick-up time delay, which is xed at 0.5 seconds.
