- Under voltage monitoring
- Monitors own three phase, 4-wire supply
- Fixed Trip level
- Adjustable Restart time delay
- Includes commissioning mode feature
- SPDT Relay output
- 17.5mm wide, DIN Rail mount
When power is applied, the output relay will energise after the set time delay provided the monitored voltage is above the fixed Under voltage trip level. The relay will de-energise if the voltage on one or more of the phases decreases below the trip level.
The commissioning mode allows the internal relay to energise immediately and avoids the minimum 5 minute waiting period.
