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.
