HRN-64 | Protecting voltage relay

  • It serves to control supply voltage for appliances sensitive to supply tolerance, protection of the device against under/overvoltage.
  • For the difference between HRN-3x and HRN-6x - see a graph of the function
  • HRN-33, HRN-63
    • monitors voltage in range AC 48 - 276V
    • it is possible to monitor the level of overvoltage and undervoltage separately
  • HRN-34, HRN-64
    • like HRN-33, but voltage range is DC 6 - 30V
      • monitoring of battery circuits (24V)
  • HRN-35
    • like HRN-33, but independent output relays for each voltage level
    • it is possible, for example, to switch a different load than for undervoltage by the output for overvoltage
  • HRN-37, HRN-67
    • monitors the voltage in range AC 24 -150V
    • it is possible to monitor the level of overvoltage and undervoltage independently
  • An adjustable time delay for all types is 0 - 10s (to eliminate short voltage drops or peaks).
  • Voltage Umin adjusted as % of Umax.
  • 3-state indication - LEDs indicating normal state and 2 fault states.
  • the device is powered from the monitored voltage (measures the level of its own power supply)
  • single-phase design, 1-MODULE, DIN rail mounting.
