Audio Authority Corporation of Lexington, Kentucky has announces the availability of its Enhanced Flight Model 2860A Ground Power Unit (GPU). This updated model now provides up to 60-amps continuous, 28-volt DC power from an ordinary 120-volt AC wall receptacle. This provides ample ground power for most piston, turboprop, and jet aircraft up to 12,500 lbs. The device has been tested with a wide variety of aircraft including Cessna, Piper, and Cirrus piston singles; Meridian, TBM, PC12, Mustang, CJs, Lear 31A, King Air, and Twin Commanders.

Design improvements include digital output meters for both voltage and current, a detachable front-panel output cable, and nylon bumper/cleats to provide protection and convenient input and output cord storage. Its lightweight, easily portable design utilizes the latest high-efficiency switching-mode power technology to provide massive amounts of stable, noise-free DC power that perfectly replicates the in-flight electrical environment.
