Top Overvoltage Undervoltage Fluctuation Reviews

Omron K8DS-PH1 Phase Monitoring Relay

  • The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail..
  • Use 5 indicators to indicate: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage and undervoltage..
  • Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S..
  • Overvoltage protection means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC..
  • Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action..
