Audio Authority Corp. of Lexington, Ky, has introduced 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, which provides ample ground power for most piston, turboprop, and jet aircraft up to 12,500 lbs., according to company officials.
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, officials added.
Other 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. The new 2860A is priced at $1,095 with a 14-day return policy and a 1 year limited warranty.
The 2860A GPU’s lightweight, portable design utilizes the latest high-efficiency switching-mode power technology to provide massive amounts of stable, noise-free DC power that replicates the in-flight electrical environment, company officials said. Common uses include:
- Power for a thorough pre-flight inspection and battery top-off
- Cockpit procedures training, familiarity and practice
- Avionics testing, programming, and database updates
- Cabin heating and ventilation
- Entertainment systems
- Aircraft systems troubleshooting and maintenance
