HRN-33

HRN-33 | Voltage monitoring relays in 1P - AC

• 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
• Monitors voltage in range AC 48 - 276 V.
• Umax and Umin can be monitored independently
• Voltage Umin adjusted as % of Umax.
• 3-state indication - LEDs indicating normal state and 2 fault states.
