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.
