To solve the problem of over and under voltage, we are engaged in offering microprocessor based Under & Over Voltage Relay. Our offered voltage relay is based on latest technology and fitted in 96 mm X 96 mm sq. enclosure. If electrical products are connected with load that is more than the settable limits of voltage, this voltage relay indicates the power cut with alarm.

Applications:

Water purification and treatment plants
Paper and pulp industry - washers, head box feed, bleachers
Sugar industry - Pan alteration, Dialer automation
Chemical and petrochemical industry
Primary & auxiliary temperature controller for boilers
Water pumping stations, power plants and Under & Over Voltage Relay heat treatment furnaces
Seven segment LED display is provided for indication of settings and actual conditions

Principle of operation:

This voltage relay is based on the principle of precise sensing of actual voltage and w.r.to pre-set levels of permissible over & under voltage. Offered voltage relay activate protection circuit when the voltage crosses pre-set limit. Further, inform about this by activating alarm and indicating using LED.

Salient features:

Microprocessor based
Designed by the experts
Made using quality approved glass epoxy boards and integrated circuits
Easy to configure
User friendly
Absorb power supply transients using filter circuit and stabilized power supply
Stable display & display output help to view distance of more than 4 meter

Burn - In:

Prior to delivery, offered voltage relay is checked under in electrically energized conditions for duration of 48 hours for ensuring the reliable performance and perfect design.
