INTRODUCTION
The
Power Force 50™
supplies 50-watts of continuous power, with an 80-watt
peak, via a household-type outlet that is ready to deliver 110-volt AC power
whenever and wherever it is needed. Simply, fully charge before use and turn ON
the power switch to operate small electronic devices such as laptop computers,
portable radio/cassette/CD players, color TVs (up to 50 watts), cellular phone
and camcorder battery chargers, and more.
The
Power Force 50™
is equipped with an ON/OFF switch and power/charging
indicator light. The AC receptacle is fully marinized, weather-proof and fused.
Added safety features include:
• electronic circuit protection that prevents damage due overloading or insufficient
ventilation;
• automatic shutdown to prevent damage to vehicle’s battery.
Please read the following information carefully before use, to ensure reliable
service and complete safety. Pay particular attention to the CAUTION and
WARNING statements that are provided.
HOW THE
Power Force 50™
INVERTER WORKS
The
Power Force 50™
inverter is an electronic device that converts low voltage
DC (direct current) electricity from a battery to standard 110-volt AC (alternating
current) household power. In designing the
Power Force 50™
, Vector™ has
incorporated design techniques previously employed in computer power supplies.
The result of these design innovations is a smaller, lighter and easier-to-use
power inverter.
Principle Of Operation
The
Power Force 50™
inverter converts power in two stages. The first stage is a
DC-to-DC conversion process that raises the low voltage DC at the inverter input to
14.5-volts DC. The second stage is the actual inverter stage that converts the high
voltage DC into 110-volts, 60 Hz AC.
The DC-to-DC converter stage uses modern high frequency power conversion
techniques that have replaced the bulky transformers found in less technologically
advanced models. The inverter stage uses advanced power MOSFET transistors in
a full bridge configuration. This ensures excellent overload capability and the
ability to operate reactive loads like lamp ballasts and small induction motors.
