HRN-63 | Voltage monitoring relay

• serves to monitor the supply voltage for appliances prone to supply tolerance, protection of equipment against undervoltage / overvoltage ...
• difference between HRN-3x and HRN-6x series - see graph function
• HRN-33, HRN-63
  • monitors voltage in the range AC 48 - 276V
  • it is possible to monitor the level by overvoltage and undervoltage separately
• HRN-34, HRN-64
  • as HRN-33, but with a level range of monitored voltage DC 6 - 30V
  • this range is predestined for monitoring battery circuits (24V)
• HRN-35
  • like HRN-33, but independent output relays for each voltage level
  • it is thus possible, for example, to switch a load other than for undervoltage with the output for overvoltage
• HRN-37, HRN-67
  • like HRN-33, 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).
• the lower voltage level (Umin) is set in% of the upper level (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
