28V DC Aircraft Ground Power Units (GPU / Rectifiers)
Buy new, used, and refurbished 28V DC hangar-powered rectifiers on 3-phase or single-phase input voltage. These new units provide the aircraft DC power in the hangar or on the ramp. Some operators need these units to update their onboard computer systems, service the aircraft, or assist the aircraft batteries during engine starts.
Three-phase input voltage is required from your hangar or local facility for these GPUs. Most hangers are setup with three-phase power.

These GPUs only need single-phase input voltage from your hangar or local facility, but they are not as efficient as the three-phase units above and only should be considered if you have no other option.
