About ATD Inverters.

A TD, an inno vator in port able inverter design, has devel oped a new line of super-e f fici ent 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 hig h 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 referre d to as the "star ting 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 requirement s. 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 equi pmen t, check th e owner's
manual or contact the manufacturer to determine if the device you are using is compatible with
a modified sine wave source.

Multiply: AMPS X 110 (AC voltage) = WATTS

This formula yields a close approximation of the continuous load of your a ppl ia nce

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.

To determine whether the inverter will operate a particular piece of equipment or appliance, run
a test. The inverters are designed to automatically shut down in the event of a power overload.
This protection feature prevents damage to the unit while testing appliances and equipment
with ratings in the 3000 watt range.
If an appliance in the 3000 watt range will not operate properly when first connected to the
inverter, turn the inverter rocker switch ON(I), OFF(0), and ON(I) again in quick succession. If
this procedure is not successful, it is likely that the inverter does not have the required capacity
to operate the appliance in question.

Important

z The inverter is designed to operate from a 12-volt power source only. Do not attempt to

connect the inverter to any other power source, including any AC power source.

z Do not attempt to extend or otherwise modify the 12-volt power cord attached to your

inverter.

z 110 volts of current can be lethal. Improper use of your inverter may result in property

damage, personal injury or loss of life.

A. ON/OFF Switch. The current flowing from the power source to the inverter is controlled by

this switch.

B. 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. Immediately turn off the appliance if
this occurs The High Speed Cooling Fan automatically activates excessive temperatures
are detected. When this occurs turn off the inverter and determine the cause of the
overload before turning the inverter and the appliance back on.

C. 110v AC Outlets, recommend each outlet use an appliance not more than 3000W. Each

outlet with 110V, 1.5A Max.

D. High-Speed cooling fans. When the temperature inside the inverter exceeds the limits of

safe operation the Cooling Fan automatically turns on to cool the inverter. When the
temperature has lowered to a safe operating mode, the fan will shut off. The fan is not

designed to run continuously.
E. Positive Power Input Terminal.
F. Negative Power Input Terminal.
G. Remote Housing Set.
H. Display reading selection switch
J. Battery voltage and inverter output wattage digital meters.

WATT Reading: When selection switch at "watt" position. The digital number displays

"watt" reading.

VOLT Reading: If switch is on the "volt" position. The digital number will display input

"voltage" reading. These readings are the result of measuring the voltage in both the

positive and negative input terminals on the inverter. In a high voltage draw the display will

show a low voltage level due to the drop in volts that occurs between the positive and

negative input cables.
K. Ground Terminal
