Voltage Monitoring Relays

Novatek Electro India Pvt Ltd offers a range of single-phase Voltage Monitoring Relays, Model RN-102. The RN-102 voltage monitoring relay is designed to de-energise an industrial/appliance single-phase 220 V/50 Hz load in case of inadmissible voltage variations in the mains with subsequent automatic re-energizing after the circuit parameters recovery. Load is connected to the relay either directly via relay terminals or through a magnetic starter, depending on the wattage. The relay can operate in four independent modes: voltage monitoring relay; minimum voltage monitoring relay; maximum voltage monitoring relay; time relay with a restart delay. The device front panel features load status indicator (on/off) and three-digit, seven-segment display, which displays (depending on the device status): actual RMS voltage; accurate value of the set-up parameter; time remaining till automatic load re-energizing; emergency de-energizing the load (RMS voltage flashing). The variable pot knobs on the front panel allow for setting: the maximum allowable voltage tripping threshold; the minimum allowable voltage tripping threshold; time delay for load re-energizing after the circuit parameters recovery. The RN-102 equipment includes a surge protector which protects the switched load against high-frequency and high–voltage impulse interference. The company also offers Single Phase Voltage Monitoring Relay, Motor Protection Unit, Voltage Monitoring Relays, etc.
