12 Volt Power Outlet Receptacle Description and Operation
|
The accessory power receptacle in the trunk of the vehicle is supplied with battery voltage all the time. The accessory power receptacles located in the console and the cigarette lighter receptacle are supplied battery voltage when the ignition is on or in the accessory position
|
230 Volt Power Outlet Receptacle System Description
|
The electrical outlet system for AC accessories comprises the accessory DC/AC inverter and the accessory power receptacle 220V AC. The accessory DC/AC power inverter converts 12V DC to 220-230V AC at 50 Hertz (Hz) in order to drive AC units. The accessory DC/AC power inverter module provides up to 150 watts of power. The accessory power receptacle - 220V AC provides the usual connection for AC powered devices.
|
230 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 - 220V 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 - 220V AC, the normally open switch in the accessory power receptacle - 220V AC, closes. When the accessory DC/AC power inverter module detects the voltage from the accessory power receptacle - 220V AC switch, the inverter module begins to supply 220-230 V AC to the accessory power receptacle - 220V AC after a 1.5 second delay. The accessory AC power system is protected against circuit overload and circuit shorts to ground.
|
230 Volt Power Outlet Receptacle Isolation Fault Protection
|
The accessory AC/DC power control module contains a ground fault circuit interrupter (GFCI). GFCI monitors the 230 V circuit for the following conditions:
|
•
|
The line A or line B circuit becomes shorted to the vehicle chassis ground
|
|
•
|
The current flow through the line A circuit and the line B circuit differs from each other by greater than 6 mA
|
If any of the above conditions is detected, the accessory AC/DC power control 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.
|
230 Volt Power Outlet Receptacle Overload Shutdown
|
The accessory AC/DC power control module will turn OFF if the current in the 230 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.
|
230 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 accessory power receptacle - 220V AC, and then plugged into the accessory power receptacle - 220V AC.
