400HZ / 28VDC Combination Aircraft Ground Power Unit

Unitron’s dual output, solid-state, AC/DC Ground Power Unit supplies simultaneous 400Hz AC and 28VDC power from a single unit and provides either 425- or 600-amps continuous power.  By combining the output of two Unitron GPUs into a single solid-state unit, the configuration reduces operating and maintenance costs, as well as, conserving valuable space on the ramp and in hangars thus easing congestion.

Unitron AC/DC GPUs are available in mobile, towable, boarding bridge-mount, or fixed configurations, accommodating a variety of applications.
