Digital Voltage Relay

Since our commencement, we are engaged in manufacturing, supplying, exporting and trading Digital Voltage Relay. Has user friendly settings, these relays monitor the line to line voltages continuously, owing to which these are widely used to protect the synchronous and induction motor of any HP rating. Provided with LED and LCD where the faults are displayed, our offered relays have superior functionality. Besides, these relays are applicable in transformer feeder panel, distribution boards and voltage regulators.
