  • It serves to control supply voltage for appliances sensitive to supply tolerance, protection of the device against under/over voltage.
  • HRN-3x is band voltage relay, HRN-6x is over/under voltage relay.
  • Like HRN-33, monitors voltage in range AC 24 -150 V
  • It is possible to monitor level of overvoltage and undervoltage independently
  • Voltage Umin adjusted as % of Umax.
  • 3-state indication – LEDs indicating normal state and 2 fault states.
