DC/AC Inverter and AC Power Point

High-Voltage Converter/Inverter

Principles of Operation - DC/AC Inverter and AC Power Point

The DC/AC inverter converts 12 volts DC to 110 volts AC to power a device that uses AC electricity with a rating of less than 150 watts. The 110 volts AC created by the inverter will measure differently than a conventional AC outlet (utility-generated) with some multi-meters. The AC power point will automatically shut off if the load exceeds 150 watts, to help prevent damage to the inverter or load. The inverter supplies 110 volts AC power only when the ignition is in the ON/START position. This reduces the draw on the 12-volt system when the vehicle is not running. The AC power point is equipped with a green LED that indicates the system integrity.

- Green LED illuminates continuously - ignition in ON/START and system is operating normally.
- Green LED flashes continuously - ignition in ON/START and a fault is detected.
- Green LED does not illuminate - ignition is not in ON/START, fault on the RUN/START circuit input to the DC/AC inverter or the DC/AC inverter is not powered (fault with DC/AC inverter B+ or ground circuits).

Short circuits, overloads or overheating of the inverter will cause the green LED to flash and the power to be cut off to the outlet. If the LED is flashing, the problem must be corrected (short circuit or excessive load). If the DC/AC inverter is overheated, it must be allowed time to cool off (without the load connected). Refer to the Owner's Literature for a list of appropriate electrical loads/devices that can be used.
