Power Force 50™ Output Waveform
The AC output waveform of the Power Force 50™ is known as a "quasi-sine wave"
or a "modified sine wave". It is a stepped waveform that is designed to have
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 motors.
The modified sine wave produced by the Power Force 50™ inverter is designed
to have an RMS (root mean square) voltage of 110 volts, which is the same as
standard household power. Most AC voltmeters (both digital and analog) are
sensitive to the average value of the waveform rather than the RMS value. They are
calibrated for RMS voltage under the assumption that the waveform measured will
be a pure sine wave. These meters will not read the RMS voltage of a modified
sine wave correctly. They will read about 20 to 30 volts low when measuring the
output of the Power Force 50™ . For accurate measurement of the output voltage
of this unit, use a true RMS reading voltmeter such as a Fluke 87 , Fluke 8080A,
Beckman 4410, or Triplett 4200.

POWER SOURCE REQUIREMENTS

The Pocket Generator™ battery must provide between 10.5 and 14.5 volts DC
and must be able to supply the necessary current to operate the load. To obtain a
rough estimate of the current (in amperes) the power source must deliver, simply
divide the power consumption of the load (in watts) by 10.
Example: If a load is rated at 50 watts, the power source must be able to deliver:
50 ÷ 10 = 5 amperes

Connection To Load

Connect the Pocket Generator™ to the vehicle's cigarette lighter socket using the
cigarette lighter plug provided. The Power Force 50™ is equipped with a
standard AC household-type receptacle. Plug the cord from the equipment to be
operated into the AC receptacle. The green LED indicator will illuminate to indicate
that the unit is functioning. Make sure the load requirements of your equipment are
within the parameters of the Power Force 50™ output. If so, turn on the equipment.
