• Under and Over voltage monitoring (Window)
  • Suited to High Voltage supplies – 575V or 600V
  • Detects incorrect phase sequence, phase and neutral loss
  • Adjustable Trip levels and Time delay
  • SPDT Relay output
  • 35mm 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, the phase sequence correct 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.
