114 Amps of Reliable 28V Ground Power
The M2875-114 delivers up to 114 amps of continuous 28V DC power, making it an ideal solution for demanding ground operations.
Whether you're an aircraft owner, mechanic, avionics installer, MRO facility, aircraft dealer, or FBO, the M2875-114 provides stable external power for the jobs that need it most.
Use it for:
-
Powered preflight inspections and battery top-off
-
Avionics and flight-deck database updates
-
Aircraft maintenance and troubleshooting
-
Cockpit training and procedures
-
Mobile MRO operations
By powering the aircraft from the ground, operators can perform extended maintenance, avionics, and training tasks without relying on the aircraft's battery or engine.
Full Power When You Need It
One of the biggest advantages of the M2875-114 is its flexible AC input.
The unit accepts 90–264V AC, allowing it to adapt to a wide range of electrical environments. From a standard 115/120V outlet, the M2875-114 can provide more than 70 amps of continuous output. Connect it to 200–260V AC and the GPU can deliver its full 114-amp continuous output. That flexibility makes the M2875-114 equally useful in a maintenance hangar, shop, or field-service environment.
Designed as a Workhorse
The M2875-114 isn't about adding complexity for the sake of complexity. It's designed to be a straightforward, dependable source of aircraft ground power.
Large digital displays provide easy-to-read voltage and current information, while the adjustable output can be set from 27.5 to 29.0V DC for applications where precision voltage matters.
The unit also incorporates protection against overload, over-voltage, overheating, and short circuits. And at just 18.3 pounds without cables, the M2875-114 delivers an impressive amount of power in a compact package.
Built for the Way Aviation Professionals Work
At White Lightning, we know that ground power isn't an accessory—it's an essential part of keeping aircraft moving.
That's why the M2875-114 focuses on the fundamentals: clean power, high output, flexible input, rugged construction, and dependable operation.
For operators who need advanced connectivity and additional features, White Lightning's SmartGPU offers capabilities such as wireless control, remote monitoring, battery maintenance charging, AC line monitoring, remote voltage adjustment, and programmable shutdown. But for customers looking for a high-output GPU with a straightforward approach, the M2875-114 delivers exactly what matters.
High Output. Exceptional Value.
High-capacity aircraft ground power shouldn't have to come with a high-capacity price tag.
The M2875-114 is priced at $1,895, bringing more than 100 amps of continuous 28V aircraft power within reach of more aircraft owners, maintenance organizations, avionics shops, and aviation businesses. It's another step in White Lightning's mission to make reliable aircraft ground power more accessible—backed by more than 40 years of aviation experience.
