This is a nice clean way to provide AC power to an internal AC Pump. It can turn the pump on when the system starts and turn it off when the system shuts down. It also has an alarm sound when the unit is receiving 12V power but no AC power.
Features:12V DC activated AC outputRelay function can be disabledUser selected dual modes of operationAlarm when there is no AC input powerReplaceable fuse to protect over load
Dual Mode Operation:If the switch on the bracket is set to upper position or "AUTO" mode, relay circuit is enabled. Relay board delivers AC output to the terminal block only when it detects 12V DC input.If the switch is set to lower position or "ON" mode, the relay circuit is disabled. Relay board delivers AC output to the terminal block regardless whether 12V DC input is detected. (Note: Switch is in "ON" Mode in main photo.)
