HRN-42 | Protecting voltage relay

• Relay is used for monitoring AC or DC voltage in three ranges.
• Monitors the level of voltage in two independent levels (Umin, Umax).
• Setting the monitored upper level (Umax) in % of range.
• Setting the monitored lower level (Umin):
  • in % of the set upper limit (HRN-41, function HYSTERESIS)
  • in % of range (HRN-42, function WINDOW)
• The selectable function of output contacts (independently/in parallel).
• Independently adjustable time delay of both levels (eliminating short-term drops and spikes).
• Galvanically separated power supply from monitoring inputs.
• Output contact for each monitored voltage level.
