Voltage monitoring relay

Multifunction, range 80-150 AC/DC,
1/2 output(s)

EAN: Select Variant SKU: N/A Category:


  • It is used to monitor the value of alternating or direct voltage in 1-phase circuits.
  • Supply voltage from monitored voltage.
  • Monitors voltage exceeding the upper voltage level (Umax) and falling below the lower voltage level (Umin) – according to the selected function.
  • Smooth adjustment of both voltage levels – the lower level Umin is set in % of the upper-level Umax.
  • Adjustable time delay (to eliminate short-term voltage drops and peaks).
  • Option to select functions with fault state memory (Latch).
  • The fault state memory can be reset with a button on the panel (RESET).
  • Measures true root mean square value of the voltage – TRUE RMS.
