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. RN-111 NOVATEK-ELECTRO
