Voltage monitoring relay in
1P - AC/DC HRN-37

DESCRIPTION

• 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
