- Over voltage monitoring
- Monitors own three phase, 4-wire supply
- Adjustable Trip level and Hysteresis
- DPDT Relay output
- 45mm wide, DIN Rail mount
The product monitors it’s own three-phase supply and in normal operation, the output relay is de-energised. When one or more phases increases above the set trip level the relay will energise. The phase voltages must drop below the trip level (minus the set Hysteresis) before the relay will de-energise again.
