Unitron UFC-60M-420UDC – PwrKart Mobile GPU – Dual 400 Hz AC & 28V DC, 60 kVA

The Unitron UFC-60M-420UDC PwrKart is a dual 400 Hz AC and 28V DC mobile ground power unit with a 90 kVA rating. Ideal for aircraft ground power applications in the hangar or ramp area, this lightweight GPU provides simultaneous AC and either 425 or 600 amps of continuous DC power from a single unit. Kilowatt power for the complete unit is limited to the nominal rating of the 400 Hz output of the GPU. Because a single unit can do the work of two, Unitron's AC/DC PwrKart reduces operating and maintenance costs and eases ramp congestion.
