Power Outlets Description and Operation
12 Volt Power Outlet Receptacle Description and Operation
The 12 V accessory power receptacles and cigarette lighter are supplied B+ when the ignition is on or in the accessory position.
110 Volt Power Outlet Receptacle System Description
The alternating current (AC) accessory power outlet system consists of the accessory DC/AC power inverter module and the accessory power receptacle
- 110 V AC. The accessory DC/AC power inverter module converts 12 V direct current (DC) battery power to 110 V at 60 Hertz (Hz) AC power to
operate AC powered devices. The accessory DC/AC power inverter module provides up to 150 watts of power. The accessory power receptacle - 110 V
AC provides the usual connection for AC powered devices.
110 Volt Power Outlet Receptacle System Operation
The accessory DC/AC power inverter module receives fuse protected battery voltage and is connected to the 12 V electrical system ground. The
accessory power receptacle - 110 V AC 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 receptacle - 110 V AC, the normally open switch in the accessory power receptacle
- 110 V AC, closes. When the accessory DC/AC power inverter module detects the voltage from the accessory power receptacle - 110 V AC switch, the
inverter module begins to supply 110 V AC to the accessory power receptacle - 110 V AC after a 1.5 second delay. The accessory AC power system is
protected against circuit overload and circuit shorts to ground.
110 Volt Power Outlet Receptacle Isolation Fault Protection
The accessory DC/AC power inverter module contains a ground fault circuit interrupter (GFCI). GFCI monitors the 110 V circuit for a short to vehicle
chasis ground. If a 110 V AC short to ground is detected, the accessory DC/AC power inverter module will turn OFF. The module remains OFF, until
the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 second delay.
110 Volt Power Outlet Receptacle Overload Shutdown
The accessory DC/AC power inverter module will turn OFF if the current in the 110 V circuit is greater than 3.8 A for 1 second, or 2.5 A for 10 seconds.
The module will turn ON again, when the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 second delay.
110 Volt Power Outlet Receptacle Internal Shutdown
The accessory DC/AC power inverter module will turn OFF if the B+ supply voltage is greater than 16.5 V or less than 11 V. The module will also turn
OFF if the device temperature is greater than 85°C (185°F). The module will turn ON again, after the shutdown condition is corrected, and the AC
powered device is unplugged from the outlet, and then plugged into the outlet.
