VWKE120A

May not be exact product—for reference only.

  • VOLTAGE MONITOR RELAY
  • VOLTAGE BAND
  • Adjustable Time Delay of 0.1-10 Seconds on Drop-out
  • 120VAC
  • 15A SPDT
Description Of Function As long as the monitored voltage (Un) remains within the OVER (Umax) & UNDER (Umin) voltage settings, the internal relay stays energized. If the monitored voltage falls outside this range, the relay will drop-out. The Umax dial sets the upper limit per the Overvoltage range of the product. The Umin dial sets the lower limit at 30-95% of the upper setting. This product has an adjustable time delay on drop-out of 0.1-10 seconds (t) to prevent nuisance tripping.
