The Polaris is a highly standardized, advanced design, Load Bank Series, covering the small KW ranges, 5-150kw, at common 60 and 50 hertz low voltages. The Polaris is intended for permanent installation outdoors or indoors. The product is designed for local or remote control, with standard digital HMI which accepts a sophisticated optional automation package.
The Polaris is standardized into five frame sizes. Within a frame size, the unit can be easily programmed to a discrete KW rating based upon the standard load step resolution of the frame.
