Multifunctional monitoring voltage relay - HRN-31, HRN-32/2, HRN-36, HRN-39

EAN: 8595188184946 | Code: 8494


  • Used to monitor the size of DC or AC voltage in single-phase circuits
  • Powered from a monitored circuit
  • Measurement of monitored voltage TRUE RMS
  • Monitors the exceeded upper limit of stress (Umax) and falling below the lower limit of stress (Umin) – according to the selected function
  • Continuous adjustment of both voltage limits – the lower level Umin is set in % of the upper level Umax
  • Adjustable reaction delay (to eliminate short-term voltage peaks)
  • Option to select functions with error state memory (Latch)
