Voltage Monitoring Relay :

 
 
Protection of electrical devices against Over voltage, Under voltage in the supply is one of the major issue in electrical systems.

For safe running of electrical devices, special protections that keep a continuous watch on supply conditions are very essentials.

'PROTONs VMR 1P' offer following protections along with 3 digit display showing

R-N voltage in scanning mode with precise accuracy.
LOW/HIGH voltage tripping to ensure trouble free running of Loads.

WORKING :
- In the normal run mode, display shows Phase to Neutral Voltage If there is no UV/OV fault then countdown of ON time for Relay will start on display & timer indication starts blinking & after that Relay will be ON & Phase to Neutral Voltage will be displayed continuously. If Over voltage/Under voltage fault occurs in the supply then Relay will be OFF & corresponding fault LED starts blinking.Hysterisis betwen Cut off & cut in is 10V
