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.
- 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.
