INTRODUCTION

Your new VEC1043 750 Watt Power Inverter Vehicle Power System is one in a series of the most advanced DC to AC inverters available. With proper care and appropriate usage, it will give you years of dependable service in your car, truck, RV or boat.

The VEC1043 supplies 750 watts of continuous power, in the form of two standard North American household outlets that are ready to deliver 115 volt AC power whenever and wherever you need it! The heavy-duty inverter has enough power to run most household or electronic appliances. It also comes equipped with battery clips to handle higher amperage/load applications, such as: power tools, stereo amplifiers, vacuums, etc. Added safety features include automatic shutdown and a low battery alarm to prevent damage to your battery.

This Vector Power Inverter is configured with the latest Soft Start Technology (SST). Before introduction of Soft-Start, high start-up currents from large inductive loads could shut down the inverter. Soft Start improves inverter operation. Three major features incorporated in SST include: First, gradual voltage ramp-up during inverter start-up. This eliminates failed cold starts under load. Second, output that momentarily dips in voltage and quickly recovers to allow large motorized loads to start. This eliminates almost all shutdowns from momentary overloads. Last, the inverter needs to be turned off then turned on once the overload that caused the inverter shutdown is removed.

This power inverter also incorporates a new cooling technology that directly benefits our customers. The new design more efficiently cools the power transistors, and combined with Soft Start, dramatically increases reliability and the life of the product.
