Safe, Affordable, Airframe Power for Piston and Light Turbine Aircraft
Our next generation 2800 Series GPUs achieve a remarkable 89% electrical efficiency to provide up to 2000W of power. Its cool running, switching-mode power modules provide massive amounts of stable, noise-free power from a 90-230 volt AC outlet. It will safely power the most delicate airframe systems with laboratory-grade 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, battery chargers, and other devices designed primarily to spin starter motors. Unique, ergonomic design features dual, removable cord/tool caddies.

Integral BatteryMINDer 
This GPU includes the option of an integral BatteryMINDer®, the 3-stage continuous-duty charger that maintains, conditions, and desulfates lead-acid aircraft batteries (not for NiCad or lithium). The new CEC1 series BatteryMINDer offers improved diagnostic tools and modes that extend the life of your battery. Temperature-compensated output ensures precise charging under all conditions and will never over or under-charge. Desulfation restores full capacity and extends battery life. Our exclusive Airframe Interface Kit provides everything you need for use with FAA certified aircraft. Just hand the kit to your licensed mechanic to install and document with a simple airframe maintenance log entry.

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. The operational concepts, recommendations, and instructions presented in our manuals 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 included 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 the GPU to your aircraft.
