- Under and Over voltage monitoring (Window)
- Monitors own three phase, 3-wire supply
- Independent relay outputs
- Adjustable Trip levels and Hysteresis
- 2 x DPDT Relay output
- 100mm wide, DIN Rail mount
The unit is designed to monitor a three phase, 3-wire supply for an under or over voltage condition. The Under Voltage relay de-energises when the monitored supply drops below the adjustable trip level. The relay re-energises when the supply rises above the trip level plus the hysteresis. The Over Voltage relay energises when the monitored supply rises above the adjustable trip level. The relay will de-energise when the supply drops below the trip level minus the hysteresis.
