To choose the correct aircraft GPU, confirm the aircraft’s required output type, output load requirement, connector, frequency, input and output cable lengths as applicable, input power, installation location, and environmental conditions. The most important starting point is whether the aircraft requires 400 Hz AC, 28 VDC, 270 VDC, or a combination output.
Unitron manufactures solid-state aircraft ground power systems including 400 Hz AC frequency converters, 28 VDC ground power units, 270 VDC aircraft power supplies, combination AC/DC ground power units, onboard frequency converters, cable handling systems, remote control accessories, and related aircraft ground power accessories.
Yes. Unitron aircraft ground power units are available in multiple configurations depending on the product family and use application. Common configurations include mobile, towable, fixed, and bridge-mounted units for hangars, ramps, flight lines, boarding bridges, and maintenance facilities.
The Unitron PS Series is a programmable frequency converter series designed to operate from a wide input frequency range and provide selectable 50 Hz, 60 Hz, or 400 Hz output power depending on the configuration. The PS Series is used onboard in aircraft and vehicles, as well as research laboratories, and other specialized power applications.
MRO (Maintenance, Repair and Overhaul) facilities use aircraft frequency converters to power aircraft during inspections, troubleshooting, avionics testing, software updates, lighting checks, cabin system checks, and other maintenance activities. External ground power allows technicians to work without running the aircraft engines or relying on onboard batteries.
Unitron supports military aircraft ground power applications requiring 400 Hz AC, 28 VDC, 270 VDC, or combination AC/DC power. These applications can include flight line support, maintenance hangars, depot maintenance, avionics testing, aircraft system checks, and advanced military aircraft electrical system support.
Yes. Unitron can review aircraft, hangar, MRO, flight line, military, and test-lab power requirements and recommend an appropriate ground power configuration for your specific needs. Requirements may include output type, power rating, input voltage, environmental conditions, cable length, installation type, controls, communications, diagnostics, and applicable specifications.
One Unitron GPU can support multiple aircraft types if the aircraft share compatible electrical requirements, connector types, output ratings, and operating procedures. Mixed fleets often prefer multiple output types, which is why 400 Hz/28 VDC and 400 Hz/270 VDC combination GPUs can be useful.
We are committed to providing our customers with superior service and support, beginning with the sale and installation of the product, and continuing throughout the life of the equipment. Unitron products are known for their outstanding reliability and performance.
