3-phase asymmetry, phase sequence, phase loss, 17,5mm Screw terminals, low depth

K8DS-PA monitors voltage asymmetry, phase sequence and phase loss for 3-phase, 3-wire power supplies.

  • Worldwide power specifications supported by one unit

  • Phase sequence, phase loss: Operation reaction time 0.1s maximum

  • Asymmetry: operation time setting from 0.1 to 30s

  • Reset method: automatic

  • LED indicators: Power (Green), Relay output (Yellow), Alarm output (Red)

  • Robust operating temperature: -20 to 60 ⁰C



  • 17.5 mm (w) body

  • Greater resistance to inverter noise

  • World-wide power specifications supported by one unit
