1. APPLICATION

Single phase (220V/50Hz) voltage monitoring relay RN-111M (hereinafter RN-111M) is designed

to turn OFF home used consumer equipment or industrial power load in case of unallowable voltage

fluctuations. And when the voltage parameters returned back to normal values after fluctuation – it

should automatically turn ON the power load with the user adjusted time delay.
1 ● If power load is less than 3,5 kW (16A) then RN-111M may operate with the power load by

its own output terminals;

2 ● If power load is more than 3,5 kW (16A) then it should be commutated using contactor of

appropriate power rating. So RN-111M operates with the magnetic coil of the contactor and thus

turns ON/OFF the power load when necessary. Kindly note that contactors of appropriate power

rating should be chosen by User and not supplied along with RN-111M.

RN-111M has four independent modes of operation:

11. Minimal/Maximal voltage protection relay;

22. Minimal voltage protection relay;

33. Maximal voltage protection relay;

44. Turn ON time delay relay.
On the LED digital display RN-111M indicates the value of acting voltage level and the

Open/Close (ON/OFF) state of the output terminals.
