Relee Monitorizare Tensiune
The analogically adjustable relays monitor 1-phase AC voltages (rms value) and DC voltages against the set threshold value for overshoot and undershoot. The devices differ with regard to their power supply (internal or external).
Note: For digital monitoring relays with voltage monitoring see Current, active current, voltage, power factor, and power monitoring.
Benefits
- All versions with wide voltage supply range
- Variably adjustable to overshoot, undershoot or range monitoring
- Freely configurable delay times
- Width 22.5 mm
- All versions with removable terminals
- All versions with screw or spring-loaded terminals (push-in)
Application
- Protection of a plant against destruction due to overvoltage
- Switch-on of a plant at a defined voltage and higher
- Protection from undervoltage due to overloaded supply voltages, particularly with battery power
- Threshold switch for analog signals from 0.1 to 10 V
