Voltage monitoring relays in 1 Phase
Voltage monitoring relay in 1P with adjustable levels with NEUTRAL
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.
