1. INTRODUCTION Your new Audiovox ADC700 inverter is one in a series of the most advanced DC to AC inverters available today. With proper care and appropriate us- age, it will give you years of dependable service in your car, truck, RV, boat or even airplane.
OPERATION The ADC700 inverter converts power in two stages. The first stage is a DC-to-DC conversion process that raises the low voltage DC at the inverter input to 145 volts DC. The second stage is the actual inverter stage that converts the high voltage DC into 115 volts, 60 Hz AC.
Figure 1. Audiovox ADC700 Inverter Operation ADC700 Output Waveform The AC output waveform of the ADC700 is known as a “quasi-sine wave” or a “modified sine wave”. It is a stepped waveform that is designed to have characteristics similar to the sine wave shape of utility power. This type of waveform is suitable for most AC loads, including linear and switching power supplies used in electronic equipment, transformers, and motors.
÷ 10 = 10 amperes CAUTION: The ADC700 must be connected only to batteries with a nominal output voltage of 12 volts. The unit will not operate from a 6-volt battery and will sustain permanent damage if connected to a 24-volt battery.
Make sure the load requirements of your equipment are within the parameters of the ADC700 output. If so, turn on your equipment. If an audible alarm sounds, refer to sections 2, 3 or 4 of this manual for probable...
ADC700 is easily capable of running most chargers and transformers. FUSE REPLACEMENT If the ADC700 is overloaded and the spade type fuse (s) (35A) is blown, flip up the fuse (s) replacement cover on the back of the ADC700 and replace the blown fuse (s) with a new spade type, 35 Amp fuse.
For best operating results, the inverter should be placed on a flat surface, such as a vehicle seat or floor. A power cord measuring 3 feet (1.0 meter) has been provided for easy positioning of the inverter. ADC700 should only be used in locations that meet the following criteria: DRY: Do not allow water or other liquids to come into contact with the ADC700 inverter.
Resistive loads are the easiest for the ADC700 to run; however, larger re- sistive loads, such as electric stoves or heaters, usually require more watt- age than the ADC700 can deliver on a continuous basis.
15 volts DC. Short Circuit Protection - Reverse polarity or a short circuit condition will usually result in the fuse being blown. Immediately disconnect the shorted load and replace the fuse inside the plug of the ADC700 as described in Section 3.
An alarm will sound when the voltage from the battery drops to 11.5 volts. This is an indication that the battery needs to be recharged. The user should stop operation of the electronic device at this time since the ADC700 will shut down automatically shortly thereafter, when the battery voltage drops to 9.8 volts.
However, in some instances, some interference may still be visible, particu- larly with weak TV signals. Try the following corrective measures: Position the ADC700 as far as possible from the television, the antenna and the antenna cables. Use an extension cable, if necessary.

PROBLEM: LACK OF POWER OUTPUT (Cont) Inverter in thermal shutdown condition. Inverter fuse blown. PROBLEM: LOW OUTPUT VOLTAGE Possible Causes Using average reading voltmeter. Inverter is overloaded. Input voltage below 10.4 volts. Allow inverter to cool down. Ensure there is adequate ventilation around unit.
