Preface
Thank you for purchasing our Pure Sine Wave Inverter.It is a compact and highly portable
power inverter Which has an excellent track record in the field of high frequency inverter. From
the 12V/24V DC outlet in your vehicle or boat, or directly from a dedicated 12V/24V DC
battery,this inverter can efficiently and reliably power a wide variety of house hold AC products,
such as TV, Computers,Air-conditioner etc. Please read this guide before installing or using the
inverter and save it for future reference. Due to our continuous work to upgrade and improve our
products, we may change or revise the contents of this manual instructions or any part of it
without giving any further notice.

Safety First
WARNING! Shock hazard. Keep away from children.
1-1. The inverter generate the same potentially lethal AC power as a normal household wall
outlet. Treat it as if you are using any other AC outlet.
1-2. Do not insert foreign objects into the inverter's AC outlet, fan or vent openings.
1-3. Do not expose the inverter to water, rain, snow or spray.
1-4. Do not under any circumstance, connect the inverter to AC power.
WARNING! Heated surface.
1-5. The inverter housing may become uncomfortably warm, reaching 140F(60°C) under extended high
power opeartion.Ensure at least 4 inches (10cm) of air space is maintained on all sides of the
inverter.During operation, keep away from materials that may be affected by high temperature.

WARNING! Explosion hazard.
1-6. Do not use the inverter in the presence of flammable flumes or gases, such as in the bilge of a gasoline
powered boat,or near a propane tanks. Do not use the inverter in an enclostireI containing automotive-
type, lead-acid batteries.These batteries, unlike sealed batteries, emit explosive hy-drogen gas which
can be ignited by sparks from electrical connection.
1-7. Do not connect live AC power to the inverter's AC outlets. The inverter will be damaged even if it is
switched OFF.
1-8. Do not expose the inverter to temperatures exceeding 104F (40 °).
CAUTION! Do not use the inverter with the following equipment:
1-9. Small battery operated products such as rechargeable falshlights,some rechargeable shavers, and
nightlights that are plugged directly into an AC receptacle to recharge.
1-10.Certain battery chargers for battery packs used in hand powered tools. These chargers will have
warning labels stating that dangerous voltages are present at the charger's battery terminals.
1-11.Note DC voltage of battery should be smiliar to input DC voltage of power inverter (for example
DC12V of battery should be connected with input voltage 12V of the inverter).

Pure sine wave and modified sine wave inverters
The inverter come in two types; pure sine wave power type and modified sine wave type. In the
pure sine wave power inverter, the 230V AC output harmonically follows a smooth sine wave
and is almost identical to normal mains electricity. As a result, the pure sine wave output would
be better for most appliances than the modified sine wave output.

Guidelines
Installation Conditions
For safe and optimum performance, install the inverter in a location that is:
3-1-1. Dry - Do not expose to water drips or spray.
3-1-2. Cool - Operate only in ambient temperatures between 32F (0°C) and 104F (40°C). Keep
away from heating vents or other heat producing equipment.
3-1-3. Safe - Do not install inverter in a compartment with batteries or flammable liquids, such
as gasoline or explosive vapors.
3-1-4. Wellryulbtark Allow at least 4 inches (10cm) clearance above and on all sides of the unit
for proper cooling.
3-1-5. Clean and free of dust and dirt - This is especially important if the inverter is used in a
dusty working environment. Select a Suitable Location.

Working Principle
The inverter works in two stages.During the first stage,the DC to DC converter increases the DC
input voltage from the power source(eg.A 12V battery) to 300V DC. In the second stage, the
high voltage DC is converted to the watts you need (AC) using advanced power MOSFET tran-
sistors or IGBT technology in a full bridge configuration. The result is excellent overload
capability and the capacity to operate difficult reactive loads.
Connection Method
3-2-1.Attach the ring type connector marked with redto the positive (+) DC terminal on the
inverter and attach the ring connector marked with black to the negative (-) DC terminal.
CAUTION! A reverse polarity connection (positive to negative) may damage the inverter
(Fuse). Damage caused by a reverse polarity connection would probably invalidate your
warranty
