COMBINED OVER & UNDER VOLTAGE RELAY JRV 014

Principle of Operation:

JRV 014 provides under & over voltage protection for power systems. Relay operating time is determined by set definite time. The relay measures the voltage from input PT and if the voltage is below the set threshold, under voltage stage operates and voltage is above the set threshold, over voltage stage operates and it extends a trip signal after the operating time, which is determined by set definite time. The relay output contacts are self reset type. TEST button facilitates testing of relay contacts for trip and alarm circuits.
