Three-phase voltage monitoring relay JDS
Characteristics:
Alarm signal is output by relay touching points sub-plate mounting/din-rail mounting overvoltage, undervoltage, unbalanced three parameters will be monitored at the same time. For three-phase 380V/415V 50/60Hz power supply overvoltage, undervoltage, unbalanced alarm..
