The F-400 Series is a static, solid-state AC ground power unit that converts mains supply into stable 400 Hz, 115/200 V three-phase power — the dedicated aircraft standard required by avionics, in-cabin systems, and maintenance test equipment on virtually every jet platform.

The FR-400/28 Series eliminates the need for separate AC and DC ground power units by integrating a 400 Hz frequency converter and a 28.5 V DC rectifier into one cabinet on a single trolley.

The Hatch PIT Series is a subsurface service delivery system installed flush with the apron pavement at aircraft stand positions.

The C-Coil Series is a cable management and delivery reel purpose-engineered for ground power installations where the GPU is mounted out of reach — principally beneath passenger boarding bridges, in ceiling-mount hangar rigs, and in compact gate service rooms.

The DP-50/60 Series is a fixed-installation electrical distribution pillar that brings all the power circuits a maintenance technician needs to a single, weather-resistant column at the aircraft nose or wing.

The R-28 Series is CDR Technology's dedicated DC ground power unit, purpose-built to supply the 28.5 V DC bus that drives starters, flight-deck avionics, emergency systems, and APU assist circuits on turbine aircraft and helicopters.
