Audio Authority Corp. of Lexington, Ky., has introduced its Enhanced Flight Model 2860A Ground Power Unit (GPU). This updated model 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, company officials add.
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 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. That’s $35 less than the 50-amp model it replaces, company officials note. Quantity and commercial discounts are also available.
The 2860A GPU provides ground power for aircraft owners, maintenance facilities, dealers, FBOs, and aircraft manufacturers. Its 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, according to company officials. 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
This new generation GPU is designed as an alternative to start carts, battery chargers, and other power systems designed primarily for engine starts. It will safely power the most delicate airframe electronics with laboratory-grade DC without risk of damage to sophisticated avionics and integrated flight decks, instruments, and electrical equipment, company officials said.
