11-10833   Battery: Ground Power 28V/70Amps

28-VOLT 70AMP GROUND POWER UNIT (GPU)

Safe, Affordable, Airframe Power for Piston and Light Turbine Aircraft

The Enhanced Flight 2835A GPU achieves a remarkable 89% electrical efficiency to provide up to 1,000W

of power. Its cool running, switching-mode power modules provide massive amounts of stable, noise-free power

from a 90-230 volts AC input. It will safely power the most delicate airframe systems with laboratorygrade DC

without risk of costly damage to sophisticated avionics, instruments, or electronic equipment. This new generation

GPU is designed as a practical alternative to large, expensive start carts, and battery chargers, and other devices

designed primarily to spin starter motors. Unique, ergonomic design features dual, removable cord/tool caddies.

Stable, noise-free DC power, safe for today's advanced cockpit systems.

Digital output meters for both voltage and amperes, with overload warning.

Includes detachable input and output cables with AN2551 3-pin oval plug.

Compact, lightweight design utilizes highly efficient digital switching-mode power modules for greater reliability.

Removeable caddies for cable management and tool storage.

Input: 90-230 Volts AC, 50-60 Hz, up to 9.5 Amps

Output: 28 +/- 0.5 Volts DC, up to 35 amperes continuous

Weight: 19.4 lbs (8.5 kg) without cables

Dimensions: 7.25"H x 14.6" W x 13.75"D (18.1 cm x 27.6 cm x 34.9 cm)

Note: See the Model 2835A manual for details on aircraft compatibility and start assist (piston engines only).

IMPORTANT DISCLAIMER & OPERATING LIMITATIONS: Audio Authority® authorizes this device for use ONLY

by aviation professionals, such as licensed pilots and maintenance technicians, knowledgeable about their aircraft

electrical system and batteries. Aircraft electrical systems vary widely. Many aircraft electrical systems have been

altered in the field from the original OEM configuration and these changes are often poorly documented in the aircraft

records. The operational concepts, recommendations, and instructions presented here are necessarily general and make

assumptions that do not apply to every aircraft, and may not be correct for your particular aircraft. Incorrect use of this

device has the potential to damage the GPU and/or aircraft components. It is the operator’s responsibility to read

completely and fully understand the manual, plus those sections of the Aircraft Flight Manual and Maintenance Manual

that pertain to their aircraft’s electrical system design, to determine the appropriate use of this, or any, external power

source. If you cannot do this, do not use this product. Instead, consult the airframe manufacturer or a technician familiar

with your specific aircraft type and configuration before connecting a GPU to your aircraft.
