The single-phase voltage monitoring device MU 635 is available in two designs with measuring ranges for system voltages of 20 to 100 V or 50 to 250 V. An auxiliary voltage supply is obviated since the device is powered by the measured voltage.
Principal Features
- Single-phase monitoring of DC and AC voltages by r.m.s. value acquisition
- Selection of operating mode via jumper: overvoltage mode or undervoltage mode
- Selection of designs with different measuring ranges 20 to 100 V 50 to 250 V 100 to 500 V2)
- Separate voltage supply obviated since the device is powered by the system being monitored
- Adjustable disengaging ratio
- Adjustable operate delay
- LED indicators for operation and signaling
- Output relay mode selection via jumper: energize-on-signal or normally-energized arrangement (ëopen-circuití or ëclosed-circuití principle)
