Model : W-OP2
1Ø Under and Over voltage with adjustable time delay & Selectable voltage Code : 6009
W-OP2 is a digital electronic instrument designed for AC voltage monitoring and protection in single phase system. Used in application such as under and over voltage. When the measured voltage moves outside the set-point limit, the relay will de-energize after the selected time delay (Off delay). The relay will automatically reset to energize when the input voltage is raised past the set-point plus the hysteresis value and the adjustable delay period starts. At the end of timed period the relay will automatically energize again.
