Overview

Smart, Safe, Convenient, Airframe Power The White Lightning SmartGPU is a specialized switching-mode power supply designed to provide pilots and aviation maintenance professionals with a portable, affordable source of stable, high-current, noise-free DC power that replicates the in-flight electrical environment. Its rated output is 28-volts up to 114-amps. The GPU’s intended purpose is to energize an aircraft’s main electrical bus without using the ship’s battery or engine. It will safely provide continuous power for the most delicate electronics and airframe systems up to its full rated output. The SmartGPU mobile app allows the user to monitor the power draw from the flight deck or anywhere in the hangar. SmartGPU Features S28114 - Provides up to 114A of 28V DC airframe power to accommodate the needs of turboprop and business jet operators. S28054 - Provides up to 54A of 28V DC airframe power to accommodate the needs of turboprop and business jet operators. Bluetooth and Wi-Fi* enabled for remote monitoring and control. Graphical color display with large, highly readable volt/amp output meters. Rugged, heavy-gauge aircraft cable with AN2551 external power plug. Environmental temperature sensor – shows ambient air temperature inside an aircraft hangar with customizable trigger alert settings. White Lightning Features Universal, worldwide AC input compatible. Compact, lightweight, rugged design with collapsing carry handle. Color-coded, polarized output connectors prevent voltage mismatch. High-efficiency switching-mode power technology. Forced air cooling for long term reliability. Programmable timer with safety auto-shutoff. USB ports for data downloads, firmware upgrades, and device charging. * Wi-Fi functionality is associated with battery charging only. BatteryMINDer maintenance charger is optional.

Applications

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.
