CM-PVS Three-Phase Monitoring Relays
The CM-PVS.x1 are monitoring relays for three-phase mains. they monitor the phase parameters phase sequence,phase failure,over-and undervoltage. The threshold values for over-and undervoltage are adjustable.
Monitoring of three-phase mains for phase sequence(can be switched off),phase failure,over-and undervoltage threshold values for over-and undervoltage are adjustable as absolute values tripping delay can be adjusted or switchhed off by means of a logarithmic scale ON-delayed or OFF-delayed tripping delay selectable Powered by the measuring circuit True RMS measuring principle 2 c/o (SPDT) contacts 3 LEDs for status indication
