- Product Description
⚡ ACSOON Hybrid Frequency Converter / Aircraft Ground Power Unit

400Hz GPU Diesel Mobile Power Unit – Reliable Power, Simplified
Trouble:
Modern airports and MRO facilities face increasing pressure to improve turnaround efficiency while reducing operational costs.
However, many aircraft still rely on APUs or unstable ground power sources during:
Aircraft maintenance
Avionics testing
Pre-flight inspections
Hangar operations
This leads to:
High fuel consumption
Excessive APU wear and maintenance cost
Unstable power supply during sensitive testing
Increased operational downtime
Solution:
The ACSOON Hybrid Frequency Converter / Aircraft Ground Power Unit provides a stable and reliable 115V/200V 400Hz power supply, specifically designed for aviation ground operations.
It eliminates the need for continuous APU operation and ensures consistent power during all maintenance procedures.
Result:
✔ Lower operating cost
✔ Improved maintenance efficiency
✔ Stable aircraft-grade power output
✔ Reduced APU dependency
✔ Safer ground operations
The ACSOON Aircraft Ground Power Unit is an industrial-grade 400Hz power conversion system designed for airport and MRO environments.
It converts standard three-phase AC power into stable aircraft-compatible 115V/200V 400Hz output, supporting both AC and DC aircraft systems.
Built with a hybrid frequency conversion architecture, the system ensures continuous and stable power delivery even under heavy load conditions.
This unit is widely used in:
Aircraft maintenance hangars
Airport ground support operations
MRO facilities
Aircraft system testing and diagnostics

Our Services

Quality Control
Every unit burned in – 2 hours at 60kVA, then 90kVA for 60 seconds. Same as our premium units.
Analog meter checked – Against a calibrated DMM. Must read within 2%.
Contactor cycle test – 500 on/off cycles. No welding or sticking.
Final human test – Someone runs it through a start sequence. Signs off on a paper checklist.
R&D Results
Customer request – A small airport asked for a cheaper GPU without "the computer stuff". We built this.
Display choice – Digital displays fail. Analog meters rarely do. Simple choice.
Fault lights – Used red/yellow/green LEDs. Red = fault, yellow = warning, green = run. Anyone understands it.
Knob placement – Put the voltage trim on the left, start button on the right. Muscle memory works.


Packaging and Transportation
Shipped from Xi'an – Standard wooden crate. Bolted to a skid.
Included – Input pigtail (3m), output cable (15m) with NATO plug, printed quick guide.
Manual – One sheet of paper. Double‑sided. That's it.
No USB – You don't need one.
After‑Sales Service
1‑year warranty – Covers everything. Return to Xi'an.
Spare parts (contactor, fan, voltmeter) kept in Xi'an.
Email support – We'll help. But you probably won't need it.


Qualification Certification
CE – LVD and EMC.
ISO 9001:2015 – Our Xi'an facility.
MIL‑STD‑704F – Output tested. Report on request.
FAQ
Q1: Can I add remote monitoring later?
A: No. This model has no comms port. If you need remote monitoring, buy our standard GPU400 series.
Q2: How do I know if it's overloaded?
A: The output contactor will trip. The red fault light will come on. Turn it off, reduce the load, restart.
Q3: Is this unit quieter than your standard model?
A: Same fans, same noise. About 65 dB at 1m. Not silent, not a jet engine.
Q4: Can I get a 90kVA version?
A: Yes, GPU400‑330090‑U. Same simple design, just more power.
Q5: Lead time from Xi'an?
A: 3‑4 weeks. We build these alongside our standard units.
