1.Introduction of 3-phase And Voltage Relay
ME-JVR(800-1) is Multi-function monitoring and protection device which includes timing, counting and voltage show, over-voltage and under-voltage protection, open-phase advanced microprocessor chip and nonvolatile storage technology. Chinese LCD is easy to operate, show the current supply voltage, cut off power to protect the equipment when meet over-voltage, under-voltage, phase loss and phase reversal faults. It is fit for various of passenger eievator, goods lift, hoist, machine tool and other devices which frequent start.
2.Protective Funtion of 3-phase And Voltage Relay
A.Phase Loss protection:power will be cut off during phase lose;
B.Phase sequence protection:power will be cut off during when wrong phase sequence;
C.Under voltage protection:power will be cut off during under-voltage;
D.Over voltage protectionpower will be cut off during over-voltage;
E.Phase unbalance protection;
F.Voltage display:show the current supply voltage;
G.Fault records:recording the times and the tatal time of the errors.
3.Feature of 3-phase And Voltage Relay
A.Built-in LCD and keypad afford a precise,digital setting;
B.Three-phase monitoring of phase sequence, phase loss, over- and undervoltage;
C. Adjustable over- and under voltage threshold ;
D.Independent adjustable delay time for phase sequence, phase loss, overvoltage, undervoltage;
E.Powered by the measuring circuit;
F.1 C/O & 1NC contacts;
G.with Timing, counting and faulure recording
4.Applications of 3-phase And Voltage Relay
A.Pumps;
B.Fans;
C.Blowers;
D.Motors;
E.Compressors;
