Unitron UFC-180T 180 kVA Ground Power Unit (GPU)

The Unitron UFC-180T trailer mounted PwrKart is a 180 kVA ground power unit (GPU) for servicing the largest commercial and military aircraft on the market today. This unit operates on 3 phase input voltage from your hangar or your local facility. The dual outputs provided can be single source controlled, be individually voltage regulated and line drop compensated, and configured for partial redundancy.
