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.
