VMR - 3 Phase SALIENT FEATURES : Microcontroller based technology. Voltage protection along with digital voltage readout. Wide range of supply variation. Protection against Under voltage. Protection against Over voltage. Password Protection for the set point. All the set points setable by keys. Indications for High voltage, Low voltage Relay ON & Timer indication . No separate auxiliary supply required. TECHNICAL SPECIFICATION : Supply voltage 100-300 VAC, (No auxilliary supply) Output Contacts Two changeover (N/C-C-N/O),Rating 5A at 230VAC Voltage trip setting : 240 to 300 V For OV with digital display (resolution of 1 V): 0 to 210 V For UV with digital display (resolution of 1 V)( Hysterisis between cut off & cut in is 10V) Trip Time delay Trip time for UV :Settable Default : 5 sec. Range: 1 to 60 sec. for OV : Fixed 3 sec. ON Delay Selectable by keys from 1 to 60 sec. Reset Mode Auto reset.

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 Download PDF
