- Under and Over voltage monitoring (Window) with restart delay
- Selectable Nominal voltages
- Detects incorrect phase sequence and phase loss
- Fixed Trip levels and adjustable Time delay
- SPDT Relay output
- 17.5mm wide, DIN Rail mount
The product monitors it’s own three-phase supply and for the output relay to energise, all phases must be present, the phase sequence correct and the phase to phase voltages within the fixed Under/Over trip levels. If any of these conditions are not met, the relay will de-energise.
