Congratulations on purchasing your new converter. Read
this Instruction Manual and follow the instructions carefully
before using your new converter.
This power converter is configured to supply continuous
power in the form of a 230-240 volt AC outlet and a 5 volt
USB charging port to run most household or electronic
appliances.
How this converter works
This converter is an electronic device that converts low
voltage DC (direct current) electricity from a battery to
240 volts AC (alternating current) household power. It
converts power in two stages. The first stage is a DC-to-
DC conversion process that raises the low voltage DC at
the converter input to 280 volts DC. The second stage is a
MOSFET bridge stage that converts the high voltage DC
into 240V, 50Hz AC.
Power converter output waveform
The AC output waveform of this converter is known as
a modified sine wave. It is a stepped waveform that has
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 small motors.
CAUTION: RECHARGEABLE DEVICES
Certain rechargeable devices are designed to be charged
•
by plugging them directly into an AC receptacle. These
devices may damage the converter or the charging
circuit.
When using a rechargeable device, monitor its
•
temperature for the initial ten minutes of use to determine
if it produces excessive heat.
If excessive heat is produced, this indicates the device
•
should not be used with this converter.
This problem does not occur with most of the battery
•
operated equipment. Most of these devices use a
separate charger or transformer that is plugged into an
AC receptacle.
•
The converter is capable of running most chargers and
transformers.
Power source and protective features
Power source requirements
Your converter will operate from input voltages between 11
and 15 volts DC. If the input voltage drops below 10.5 volts
DC, the converter will shut down. This feature protects the
battery from being completely discharged.
The converter will also shut down if the input voltage
exceeds 15.4 volts. This protects the converter against
excessive input voltage. Although the converter has built-in
protection against over voltage, it may still be damaged if
the input voltage exceeds 15 volts.
Your converter is engineered to be connected directly to
standard electrical and electronic equipment in the manner
described in the "Installation" section of this Instruction
Manual. Do not connect the converter to household or RV
AC distribution wiring. Do not connect the converter to any
AC load circuit in which the neutral conductor is connected
to ground (earth) or to the negative of the DC (battery)
power source.
Inductive loads, such as TVs and stereos, require more
current to operate than resistive loads of the same wattage
rating. Induction motors, as well as some TVs, may
require two to six times their rated wattage to start up.
Because these converters have a peak watt power rating,
many such appliances and tools may be safely operated.
The equipment that needs the highest starting wattage
are pumps and compressors that start under load. This
equipment can be safely tested. If an overload is detected,
the converter will simply shut down until the overload
situation is corrected. Use the front panel switch to turn off
the converter, then on again to reset it.
