Overview

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.

  • 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.

Mfg Q&A

  • Does this unit have both 12v and 24v output? No, this is 28-volt DC output only (for aircraft with 24V battery).
  • Can I use it like a starter device for my C172? No, this unit is intended for airframe and avionics power only, not for engine starts. The 70A version may be used for start assist, piston engines only.
  • Q1. What is the length of AC cable? 2 meters
  • Q2. The cable is free or option item? AC input and DC output cables are included.
  • Q3. Could you give us the 28VDC output connector specification? The output cable plug is 3-pin AN2551 (Aircraft Spruce P/N 11-03158)

Took a while to get since it was backordered but really works well on my Citation. I am on a little airport with no power carts and this saves my battery for engine starts big time

Q&A

Q: Does this unit have both 12v and 24v output?

No, this is only 28v output.

Q: Does the GPU with BatteryMINDer work outside North America?

The GPU itself may be used with almost any voltage, but the internal BatteryMINDer is only compatible with a 100-127V AC power source. In countries with other voltage standards, a compatible BatteryMINDer must be purchased and used separately.

Q: Can I use it like a starter device for my C172?

No, this unit is intended for powering up avionics units without the engine running.

Q: 1. What is the length of AC cable? 2. The cable is free or option item? 3.Could you give us the 28VDC output connector specification?

The AC cable would be 6-1/2 ft. long. This cable would come with the purchase. The 28VDC specs are 28 +/- 0.5 Volts DC, 35 Amps continuous.

Q: I was just wondering what is the input AMPs if we have a 240v supply. Thank you.

This unit has Universal input: 100-240 VAC 50-60Hz 9.5A.
