• Under and Over voltage monitoring (Window)
  • Monitors own three phase, 3-wire supply
  • Detects phase 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 must be present and the phase to phase 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.
