Auxiliary Power Outlet: Description and Operation
Power Outlets Description and Operation (120 AC Volts)
System Description
The AC/DC power outlet system consists of the following components:
*
The AC/DC INV fuse
*
The AC/DC power outlet control module
*
The 120-volt power receptacle
System Operation
The AC/DC power outlet control module converts the 12-volt DC input voltage to 120 AC volts at the 120-volt power receptacle. The AC/DC power
outlet control module provides 150 watts of power. The 120-volt power receptacle is located on the right rear interior trim panel. The AC/DC power
control module is located behind the right rear trim panel.
Circuit Operation
Battery voltage is supplied to the AC/DC power outlet control module from the 25-amp AC/DC INV fuse located in the underhood fuse block. The
AC/DC power control module is grounded directly to the right rear D-pillar. When the ignition is turned ON, ignition voltage is supplied to the 120-volt
power receptacle using the ignition 3 voltage circuit. When a 120-volt AC powered device is plugged into the 120-volt power receptacle, with the
ignition ON, the normally open plug inserted switch, located internally in the 120-volt power receptacle, closes. The AC/DC power outlet control module
detects an ignition voltage signal on the 120 VAC Inverter control circuit and the AC/DC power outlet control module enables the 120 AC volts to the
120-volt power receptacle.
