Modern avionics operate on 400Hz AC electrical grids to drastically minimize weight by utilizing smaller magnetic cores inside aircraft motors and alternators. Our factory-grade GPUs execute double-conversion processing (AC-DC-AC) using high-efficiency insulated gate bipolar transistors (IGBT) to convert local 50Hz/60Hz grid power into clean, low-distortion (THD < 2%) 400Hz power for sensitive onboard electronics.
Airport operations cannot afford downtime. Our custom outdoor Ground Power Units feature structural shells rated to IP55 or IP65, protected by hot-dip galvanized coating and multi-layer polyurethane painting to combat coastal corrosion, extreme humidity, and sandstorms. From arctic temperatures of -40°C with automated pre-heating loops to desert heat of +55°C, internal systems remain stabilized.
By shutting down the aircraft’s fuel-hungry auxiliary power unit (APU) during gate turns and connecting to our solid-state or energy storage GPUs, airlines reduce fuel burn up to 95%. This drastically curtails engine wear and tear, slashes gate-area carbon emissions, and ensures a quiet, healthy working environment for tarmac personnel.
| GPU Configuration | Typical Power Capacity | Primary Efficiency Source | Optimal Ground Application |
|---|---|---|---|
| Solid-State Frequency Converter | 90kVA - 180kVA | Direct Grid Conversion (Efficiency ≥95%) | Fixed passenger gates, hangars, test bays |
| Diesel-Powered Mobile GPU | 90kVA - 140kVA | Ultra-Low Emission Tier 4 / Stage V Engines | Remote aprons, military deployments |
| Lithium BESS Energy Storage GPU | 90kVA - 180kVA (Battery Powered) | Recouped Grid/Solar Energy (Zero Tarmac Emissions) | Smart, green-oriented commercial airport hubs |
Pioneering the next era of smart GSE with artificial intelligence, localized grid charging, and clean energy storage integration.
As international aviation frameworks target carbon neutrality by 2050, the demand for fossil-fuel-free ground support equipment is growing. Our technology roadmap focuses heavily on replacing traditional diesel ground power units with advanced lithium-iron-phosphate (LiFePO4) Battery Energy Storage Systems (BESS) and green hydrogen fuel cells.
By implementing intelligent, variable-frequency output drives, our systems optimize power delivery dynamically. When an aircraft's cabin systems run at low loads, the converter automatically throttles output losses, reducing thermal footprint and drawing up to 20% less energy from the municipal grid compared to static legacy converters.
Future milestones focus on vehicle-to-grid (V2G) integrations, enabling parked towable GPUs to pump power back into the airport microgrid during peak electricity pricing periods.

Our manufacturing plant combines intelligent automation with structural craftsmanship. By utilizing CNC laser cutting centers and robotic welding systems, we guarantee high structural integrity for all dollies, trailers, and ground power chassis.
Our supply chain integration ensures that critical components—from military-spec IGBT modules to marine-grade hydraulic cylinders—are sourced directly, reducing lead times and protecting clients against supply bottlenecks.
Every single Ground Power Unit (GPU) goes through strict test protocols before leaving the factory. These include load-bank stress testing under varying power factors, thermal imaging validation, and electromagnetic compatibility (EMC) testing inside specialized engineering labs.
Providing global commercial airlines, defense commands, and airport ground handlers with reliable support equipment.
Fast flight turns require highly reliable ground equipment. Our towable and solid-state GPUs feature quick-connect cabling and user-friendly touch screens to minimize operator errors. Interlocks prevent operators from moving the equipment while cables are still connected to the aircraft receptacle.
Designed for deployment on tactical dirt runways, our diesel-driven mobile GPUs are housed in acoustic containment shelters. These trailers feature high ground clearance, heavy-duty suspension, and military-standard (MIL-STD-704F) power conditioning to support advanced combat avionics systems.
We work directly with airline engineering teams to design ground support equipment to their exact requirements. We customize dimensions, structural load limits, hydraulic pressure lines, climate outputs, and visual branding schemes to integrate smoothly with existing equipment fleets.
Our aviation ground equipment meets or exceeds the industry's most demanding safety and quality standards, including IATA AHM (Airport Handling Manual) 910, 913, and 972, as well as ISO 6858 specifications for aircraft ground electrical power.
We provide localized technical assistance and dispatch engineering teams globally to handle complex on-site commissioning and training programs. This ensures ground crews can operate and maintain the equipment safely.
Our global spare parts centers maintain stock levels for critical components. We guarantee rapid delivery of electrical contacts, contactors, structural components, and hydraulic replacement seals to keep your ramp operations running smoothly.
Detailed technical answers for airport procurement managers, airline engineers, and ground operations directors.
400Hz AC units are designed to power standard commercial aircraft, such as Boeing and Airbus fleets, which use high-frequency AC power systems to minimize onboard wiring weight. 28.5V DC units are designed for regional turboprops, helicopters, and smaller business jets that use low-voltage DC starting and electrical networks. Our factory designs and manufactures custom dual-output GPUs that supply both 400Hz AC and 28.5V DC from a single unit.
Solid-state frequency converters connect directly to the airport's electric grid, achieving high efficiency (often over 95%), minimal maintenance costs, and zero noise or local emissions. Mobile diesel GPUs run on internal combustion engines, making them ideal for remote aprons and military operations where grid access is limited. Choosing between them depends on your gate infrastructure and mobile deployment requirements.
Our equipment is built to meet major global aviation standards, including ISO 6858 for ground electrical power quality, IATA AHM 910/913/972 for ground support equipment safety, and CE/UL certifications. We also comply with MIL-STD-704F specifications for military applications, ensuring clean power delivery without voltage spikes or frequency drift.
