Unitron's PwrKart™ Series includes lightweight 400 Hz mobile converters for aircraft ground power applications in the hangar or ramp area. With the lightest weight-to-power rating ratio in the market, all Unitron mobile units are easily maneuvered by a single person within the hangar environment. This eliminates the expensive towing equipment or additional labor needed to move other GPUs.Output power ratings for the 400 Hz mobile PwrKart™ range from 15 kVA to 90 kVA. Larger power ratings are available in towable, fixed, and bridge-mounted configurations. In addition, Unitron offers 28v DC and combination AC/DC GPU.
