- Under and Over voltage monitoring (Window)
- Monitors own three phase, 4-wire supply
- Detects phase and neutral loss
- Adjustable Trip levels and 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 (and neutral) must be present and the phase to neutral voltages within the set Under/Over trip levels. If any of these conditions are not met, the relay will de-energise. This product operates irrespective of phase sequence.
