The single-phase voltage monitoring device MU 633 also encompasses several measuring ranges and will handle system voltages ranging from 1 V to 500 V.
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
- Overall measuring range of 1 V to 500 V divided into four partial measuring ranges
- Selection of partial measuring range via connection terminals
- High overload rating
- 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)
