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
