- Reverse Power monitoring
- Designed to monitor AC generators or boosting mains supplies
- Suited to 3-wire, three phase supplies
- Can be used with external CT
- DPDT Relay output
- 100mm wide, DIN Rail mount
The product is designed to monitor AC generators operating in parallel or for boosting mains supplies. If the current in the supply being monitored is reversed to a value greater than the adjustable trip point, the relay will energise after the time delay (user adjustable). The relay will de-energise when the current drops below the trip point minus the hysteresis. Accurate setting of the trip point and time delay will ensure protection against “motoring” in the event of generator failure and prevent tripping due to surges encountered during synchronising.
