Designed specifically as an industrial UPS system for the specific needs of the IT industry, the 4300 Series boasts one of the largest input voltage/frequency windows in the industry, which extends useful battery life. Features include true online double-conversion, an input power factor better than 98 percent, and input current THD less than 3 percent.

Frontend IGBT design allows the 4200FA to work optimally from zero to 100 percent load with less than 3 percent THD on the input, allowing for generator single-sizing. Optional matching battery cabinet and maintenance bypass cabinet allow for sixty combinations of three-phase/three-wire and three-phase/four-wire input/output voltages. Comes with a standard three year warranty.
