| Series Description: Voltage monitoring relay in 3P with range switch |
- It is used for monitoring of voltage, power failure, sequence and asymmetry of phases in a 3-phase voltage system.
- Wide range of the monitored voltage with automatic selection of a lower/higher range.
- It measures actual voltage eff ective value - TRUE RMS.
- Fixed overvoltage level (Umax), adjustable undervoltage level (Umin).
- Adjustable time delay (t2) for elimination of short-time voltage peaks.
- Adjustable time delay (t1) after switching on or with a return from the faulty state.
- Adjustable asymmetry level with optional switching off .
- Reset of the error in the memory using a pushbutton on the panel or external opening contact.
