General Aviation Ground Power Unit Main Features
- Dual Voltage Output (Optional): Primary 28.5VDC output with a front-panel selector switch for 14VDC to support older or specific light aircraft models.
- Solid-State Reliability: Utilizes modern switching technology for high efficiency, low weight, and minimal maintenance compared to old-fashioned transformer units.
- Essential Protections: Built-in over-voltage, over-current, and reverse polarity protection (via external contactor) safeguard both the GPU and the aircraft.
- User-Friendly Interface: Features a voltmeter/ammeter display, power on/off switch, output enable, and fault indicator lights for straightforward operation.
Why Choose ACSOON General Aviation Ground Power Unit?
- Dedicated to General Aviation: Tailored output (28VDC/14VDC) perfectly matches the electrical systems of most single and twin-engine piston aircraft.
- Compact & Highly Mobile: Lightweight design on a wheeled cart or as a bench-top unit allows easy movement around crowded hangars and ramps.
- Simple & Safe Operation: Features intuitive push-button controls, clear status indicators, and essential protections for worry-free use by students and technicians.
- Excellent Cost Efficiency: Provides reliable aircraft-grade power at an accessible price point for training academies and small operators.
General Aviation Ground Power Unit Application Areas
- Flight Training Academies: Daily starting and ground power for fleets of Cessna, Piper, Diamond, and other training aircraft.
- Private Aircraft Hangars: Reliable power for owner-operated aircraft during pre-flight and maintenance.
- Aviation Maintenance Shops (MRO): Essential tool for testing and servicing the electrical systems of light aircraft.
- FBOs (Fixed-Base Operators): Offering ground power services to visiting general aviation traffic.
Our Services
01
Quality Control
- Component-Level Testing: All switching transistors, diodes, and control boards are tested for function and rated performance.
- Full-Load Thermal Test: Each unit operates at its maximum rated DC current to verify thermal stability of heatsinks and components.
- Voltage Accuracy & Ripple Check: Output voltage setpoint accuracy and DC ripple are measured and adjusted to meet specifications.
- Functional Safety Verification: All protection circuits are tested by simulating fault conditions to ensure they engage correctly.
02
R&D Results
- Optimized for Light Aircraft Loads: Electrical design focuses on the typical starting and continuous load profiles of piston aircraft engines and avionics.
- Enhanced Cooling for Intermittent Duty: Developed a fan control algorithm that provides aggressive cooling during high-current start cycles and quiet operation during standby.
- Robust Connection System: Designed and sourced high-current, aviation-style output connectors and cables that are durable and easy for ground crews to handle.
- Compact Chassis Design: Achieved a small footprint through efficient component layout, making the unit easy to store and maneuver in space-limited hangars.
03
Packaging and Transportation
- Ready-to-Use Packaging: The wheeled cart unit is shipped fully assembled, wrapped in protective plastic, and secured to a pallet.
- Basic Protective Crating: For bench-top models or long-distance export, a simple but effective wooden crate with foam lining is used.
- Included Accessories: Standard shipping includes the operator's manual, test report, and necessary power input cables.
- Economical Global Shipping: Due to its relatively compact size and weight, it can be shipped cost-effectively via air or sea freight worldwide.

FAQ |
|---|
| Q1: What types of aircraft is this GPU designed for? |
| A: It is designed for piston-engine general aviation aircraft, including common trainers (Cessna 172, Piper Archer), single-engine and twin-engine private aircraft, and some helicopters that use 14V or 28V DC electrical systems. |
| Q2: Can it be used to jump-start an aircraft with a completely dead battery? |
| A: Yes, its high current output (e.g., 300A or 400A) is designed to provide the necessary power to crank an engine and can also charge a depleted battery. Always follow the aircraft manufacturer's ground power procedures. |
| Q3: What is the main advantage over using the aircraft's own battery for ground operations? |
| A: It preserves the aircraft battery's life by taking the load off it during extended pre-flight checks, avionics programming, or maintenance. It also ensures full starting power is available regardless of the battery's state of charge. |
| Q4: Is the 14VDC output standard? |
| A: The 14VDC output is an optional feature. Please specify your requirement when ordering. The standard unit provides 28VDC output, which is most common. |
| Q5: How do I connect it to the aircraft? |
| A: It comes equipped with a heavy-duty output cable terminated in standard aviation plugs (e.g., NATO-type or Anderson plugs). You connect this to the aircraft's external power receptacle, following standard safety procedures. |
