HRN-42 | Protecting voltage relay

  • Relay designed for protecting DC and AC voltage in three ranges.
  • The relay controls the size of the voltage at two independent levels (Umin, Umax).
  • two versions, HRN-41: function “HYSTERESIS” and HRN-42: function “WINDOW”
  • “MEMORY” function - to return from the error to the normal state, it is necessary to press the “RESET” button located on the front panel of the device
  • The function of the second relay (independently / in parallel).
  • The adjustable delay for eliminating short-term outages and surges for every level independently.
  • galvanically separated power supply from measuring inputs (compared to HRN-3 series monitoring relays)
  • Output contact 1x switch 16A / 250V AC1 for each monitored voltage level.
  • In 3-MODULE design, fixing to DIN rail.
