• Under voltage monitoring
  • Monitors own three phase, 4-wire supply
  • Fixed Trip level
  • Adjustable Restart time delay
  • 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.
