1. accessory AC/DC power control module always OFF 2. accessory AC/DC power control module always ON |
The accessory AC/DC power control module converts 12 volts direct current (DC) battery voltage to 220-230 volts at 50 Hertz (Hz) alternating current (AC) in order to operate AC powered devices. The accessory AC/DC power control module provides up to 150 watts of power. The accessory AC/DC power control module is connected to a chassis ground circuit and receives fuse protected battery voltage.
The accessory power outlet has an internal switch, that detects when an AC powered device is plugged into the outlet. When the ignition is ON and an AC powered device is plugged into the accessory power outlet, the normally open switch in the accessory power outlet, closes. When the accessory AC/DC power control module detects the voltage from the accessory power outlet switch, the inverter module begins to supply 220-230 volts AC to the accessory power outlet after a 1.5 second delay.
