Transitioning from mechanical rotary converters to ultra-efficient 400Hz solid-state technology. Minimizing energy losses, eliminating mechanical wear, and reducing total emissions during aircraft turnaround cycles.
Lithium-ion energy storage systems (BESS) represent the vanguard of zero-emission airports. These battery-driven mobile GPUs allow operators to charge during off-peak periods, bypassing local grid constraints.
Complying with DFS 400, MIL-STD-704F, and ISO 6858 specifications. Our wholesale GPUs guarantee steady 400Hz and 28.5V DC output, ensuring full protection for delicate modern avionics suites.
The aviation ecosystem is undergoing a dramatic shift toward sustainability and smart management. Ground Power Units (GPUs) are no longer just auxiliary power systems; they are central components of airport IoT networks. By delivering 400Hz alternating current (AC) or 28V direct current (DC) directly to parked aircraft, these systems allow passenger flights to shut down their auxiliary power units (APUs). This reduces fuel consumption and minimizes ground noise pollution, aligning operations with modern ESG guidelines.
To meet the demands of major airports and dedicated military airbases, manufacturers are focusing on dual-voltage architectures and enhanced safety interlocks. These innovations protect critical flight computers from power surges. Additionally, advancements in smart thermal management ensure that ground equipment remains highly reliable, even when operating in extreme environments.

Solid-state frequency converters use power semiconductors to convert utility power to 400Hz AC power with no moving parts. This ensures quiet, highly efficient operation and minimal maintenance. Rotary units use a mechanical motor and generator set, which requires regular maintenance and consumes more fuel.
Extreme temperatures can impact cooling capacity and electronics efficiency. Our GPUs feature advanced thermal management, IP55-rated enclosures, and dust filtration to ensure reliable performance from -40°C to +55°C.
Yes. We offer custom configurations that combine 400Hz AC and 28V DC outputs on a single chassis. This allows operators to service both narrowbody commercial jets and smaller turboprops with one unit.
Every GPU undergoes a complete testing protocol in our digital test bays.
