HOW DO POWER INVERTERS WORK

There are two stages involved in transforming 12-volt
DC (battery) power into 120-volt AC (household voltage):
STAGE 1: The power inverter uses a DC to DC trans-
former to increase the 12-volt DC input voltage from the
power source to 145-volt DC.
STAGE 2: The inverter then converts the 145-volt DC
into 120-volts AC (household voltage) using advanced
MOSFET transistors in a full bridge configuration. A
"modified sine wave" waveform is generated by this
conversion.

LED DISPLAY

The LED display identifies the current status of the
inverter.
VOLTAGE IN: The voltage of the vehicle's battery, Por-
table Power jump starter or DC power source.
VOLTAGE OUT: The voltage supplied to the device
through the AC receptacle.
POWER OUT: The power or wattage supplied to the
device plugged into the inverter.
An audio alarm will sound when any of the following
codes display. To stop the alarm, press the ON/OFF
switch:
 – The inverter is not functional. See warranty and
call Customer Service 1-800-621-5485 (Hours: 7:00 am
to 5:00 pm CST).
