Voltage monitoring relay in
1P - AC/DC HRN-42

With three input ranges for
AC / DC monitoring in
1-phase network

DESCRIPTION

  • Relay designed for monitoring DC and AC voltage in three ranges.
  • The relay controls the size of the voltage in two independent levels (Umin, Umax).
  • Setting the monitored level Umax (in % of range).
  • Setting the monitored level Umin (in % of range - for HRN-42 -function WINDOW), (in % of the set upper limit - for HRN-41 - function HYSTERESIS).
  • Function of second relay (independently/in parallel).
  • Adjustable delay for eliminating short-term outages and surges for every level independently.
  • Galvanically separated power supply from monitoring inputs.
  • Output contact for each monitored voltage level.
