RN-111 single-phase voltage monitoring relay
The RN-111 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. Load is connected to the relay either directly via relay terminals or through a magnetic starter, depending on the wattage.
The LEDs display:
- presence of voltage in the mains;
- load status (ON/OFF).
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.
