The HX7 Plus pack is a self contained Adjustable speed Drive, that is rated for outdoor use in direct sunlight With a Horsepower range from 60 Hp to 1500Hp The Plus Pack has been designed for the most brutal environments. Everywhere from the blistering heat of the desert, to the freezing arctic circle, to the corrosive offshore platforms, and even in underground mining applications. The Plus Pack is self contained, so that all that is required is the incoming power, and the motor leads. The drive is equipped with it’s own control power transformer, it’s own maintenance free cooling system, and advanced protective functions to make the drive as much a “Set it and Forget it” unit as possible. The Plus Pack springs from it’s predecessor the G3 Plus pack which earned a reputation for durability, ruggedness, and reliability. As a matter of fact, when we introduced the HX7 Plus Pack, customers expressed concern. They were happy with the G3 Plus Pack, and didn’t want it changed. The upgrade was necessary, as the components to produce the control boards were no longer available. The power platform of the Plus Pack was not redesigned, and is as reliable as the G3 Plus pack has proven to be.
