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.
