RN-101M Voltage Monitoring Relay

The RN-101M voltage monitoring relay is designed to de-energize an industrial/appliance single-phase 220V/50Hz load in case of inadmissible voltage variations in the mains with subsequent automatic re-energizing after the circuit parameters recovery. Besides, the relay: Protects the switched load against high-frequency and high –voltage impulse interference Load disconnection in case of current overload (at current higher than 16 A Indicates the circuit RMS voltage. 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
