About ATD Inverters.
ATD, an innovator in portable inverter design, has developed a new line of super-efficient power
inverters with the highest surge capability in the industry. These extremely advanced,
microprocessor controlled units run cooler and more reliable than any in their class. Their
superior surge capability allows them to start even the most difficult loads, including color
televisions, TV/VCR combinations, microwaves, refrigeration units, and even small air
conditioners! They also have the highest efficiency available (up to 90%), which translates into
longer running time and extended battery life.
Inverters convert low voltage, direct current (DC) to 110-volt alternating current (AC).
Depending on the model and its rated capacity, the inverters draw power either from standard
12 volt automobile and marine batteries or from portable high power 12 volt sources.
Getting Started
When you turn on an appliance or a tool that operates using a motor or tubes, it requires an
initial surge of power to start up. This surge of power is referred to as the "starting load" or "peak
load". Once started, the tool or appliance requires less power to continue to operate. This is
referred to as "continuous load" in terms of power requirements. You will need to determine how
much power your tool or appliance requires to start up (starting load) and it's continued running
power requirements (continuous load). Power consumption is rated either in wattage (watts), or
in amperes (amps), and this information is usually stamped or printed on most appliances and
equipment. If this information is not indicated on the appliance or equipment, check the owner's
manual or contact the manufacturer to determine if the device you are using is compatible with
a modified sine wave source.

Please read this manual thoroughly before operating your new ATD product, as it contains the information you need to become familiar with its features and obtain the performance that will bring you continued enjoyment for many years.
- Page 2 Multiply: AMPS X 110 (AC voltage) = WATTS This formula yields a close approximation of the continuous load of your appliance Multiply: WATTS X 2 = Starting Load This formula yields a close approximation of the starting load of your appliance. Most often the start up load of the appliance or power tool determines whether your inverter has the capability to power it.
- Page 3 ON/OFF Switch. The current flowing from the power source to the inverter is controlled by this switch. ON/OFF and protect LED Indicator Light. GREEN will illuminate when turn the inverter ON at normal condition. When the internal operating temperature exceeds 165 °F. this light will turn RED and the inverter will automatically shut down.
- Page 4 Selecting A Power Supply. When you operate the inverter for long periods of time combined with a high continuous load demand, the result will be a large power drain from the battery. With this in mind, check the reserve capacity of the battery you plan to use to power your inverter. To calculate the approximate power drain on your battery you will want to estimate the reserve power ("amp/hour") of the battery and the amps the inverter will require, to meet the continuous load demand of the appliance.
- Page 5 Connecting Your inverter. Make sure the ON/OFF switch located on the front panel of the inverter is in the OFF(0) position. Connect the cables to the power input terminals at the rear of the Inverter. Make sure to match the negative (Black) terminal on the 12-volt power source first. Then repeat this procedure with the positive (Red) terminal connecting a wire to the positive terminal of the 12V volt power source.
- Page 6 Television and Audio Suggestions Although these inverters are shielded and filtered to minimize signal interference, some interference with your television picture may be unavoidable, especially with weak signals. However, here are some suggestions that may improve reception. First, make sure that television antenna produces a clear signal under normal operating conditions.
- Page 7 How Power Inverters Work There are two stages in which a power inverter changes the 12 volt DC (or battery) power into 110V AC (household current). STAGE 1: The inverter uses a DC to DC converter to increase the DC input voltage from the power source to 145 volts DC.
- Page 8 When operating the inverter with an automobile or marine battery, start the engine every 30 to 60 minutes and let it run for approximately 20 minutes to recharge the battery. In the event of a continuous audible alarm or automatic shut down, turn the inverter OFF immediately.

Page 9: Troubleshooting
Troubleshooting PROBLEM: Low or No Output Voltage Reason: Poor contact with lighter socket or battery clamps Solution: Unplug and reinsert 12 volt plug or reattach battery clamps. Reason: Using incorrect type of voltmeter to test output voltage. Solution: Use true RMS reading meter. PROBLEM: Red LED Indicator On Reason: Battery voltage below 9.5 volts. -
Page 10: Specification
PROBLEM: TV Does Not Work Reason: TV does not turn on. Solution: Try turning the inverter ON/OFF/ON. Contact TV manufacturer for start up surge specifications and/or to see if the TV is compatible with a modified sine wave. A larger inverter may be required. SPECIFICATION: Max.
