Circuit/System Description

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The accessory AC/DC power control module converts 12 volt direct current (DC) battery voltage to 110-120 volt 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 a 120 volt 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 110-120 volts AC to the accessory power outlet after a 1.5 second delay.
