- Product Description
Some aircraft just need more juice. The 737 MAX and A320neo have bigger electrical systems than their predecessors. A 90kVA unit will run them, but you're close to the limit on a hot day with all the cabin loads on. The 120kVA 400Hz GPU gives you headroom.It's the same physical size as our 90kVA unit – same cabinet, same cable reel options – just with higher‑rated IGBTs and a bigger transformer. You don't give up any ramp space. You just get more power.We also sell these to military operators running C‑130J, C‑17, and other transports that specify 120kVA ground power. Same reliability, same simple controls. Just turn it on and connect.

120kVA 400Hz GPU Main Features
12‑pulse input – Keeps harmonics low. You won’t get complaints from the facility electrician.
Auto voltage compensation – Measures voltage at the aircraft plug. Adds up to 10V to make up for cable loss.
Fault memory – Stores last 10 faults with timestamps. Helps maintenance track down intermittent issues.
Wide input range – Tolerates ±15% voltage and 40‑70Hz frequency. Works on weak generator power.
Why Choose ACSOON 120kVA 400Hz GPU?
Future‑proof – Newer aircraft draw more power. 120kVA covers today's narrow‑bodies and leaves room for tomorrow's.
No derating – Full 120kVA at 50°C ambient. Tested in a hot hangar in Dubai.
Same footprint – Fits the same pit or cart as our 90kVA. No infrastructure changes needed.
Simple to run – One button for output, one dial for voltage trim. Ground crew training takes five minutes.
120kVA 400Hz GPU Application Areas
Next‑gen narrow‑body gates – A320neo, 737 MAX 8/9/10, C919. They need the extra capacity for full galley and in‑flight entertainment loads.
Mid‑size wide‑body gates – 757, 767, A330‑200. These older wide‑bodies often sit right around 90kVA. 120kVA gives you margin.
Military airlift maintenance – C‑130J, C‑27J, A400M. Their ground power specs call for 120kVA at 400Hz.
MRO hangars – When you have a mix of narrow‑body and small wide‑body, one 120kVA unit covers both.
Our Services
Quality Control
Every unit load‑tested – 120kVA for 2 hours, then 180kVA (150%) for 60 seconds. We record the temps.
Output waveform captured – Screenshot at full load. We keep it in a folder with the serial number.
Thermal scan – Covers off, full load. No hot spots over 100°C allowed.
Cable test – Output cable assembly hi‑potted and continuity‑checked. We make the cables in‑house.
R&D Results
Customer request – An airline wanted 120kVA but didn’t want a bigger cabinet. We upgraded the IGBTs and transformer while keeping the same chassis. Took two design iterations.
Fan noise reduced – Used larger, slower‑spinning fans. Moves the same air, half the noise.
Input filter simplified – The 12‑pulse rectifier already keeps harmonics low. Removed an external filter that wasn’t needed. Saved cost and reduced failure points.
Added a second ground lug – Some military users asked for two independent ground connections. Easy to add.
Packaging and Transportation
Shipped from Xi'an on a skid, stretch‑wrapped. Fits in a standard container.
Cable reel optional – Manual crank with 25m cable shipped in a separate box if ordered.
Documentation – Laminated quick guide, full manual on USB.
Export crate – Wooden box available for sea freight.
After‑Sales Service
1‑year warranty on the power module, 6 months on the cable and plug.
Spare parts kept in Xi'an. For operators outside China, we can ship express.
Email support – We check twice a day, seven days a week.
Qualification Certification
CE – LVD and EMC tested at an external lab；MIL‑STD‑704F – Third‑party test report available；ISO 9001:2015 – Our Xi'an factory；IP54 – Lab certified.
FAQ |
|---|
| Q1: Do I really need 120kVA for a 737 MAX? |
| A: Depends on your configuration. For a MAX 8 with standard seating and no extra galley, 90kVA works. If you have lie‑flat seats, multiple ovens, and the full IFE package, you’ll want the 120kVA. Check your aircraft’s load sheet. |
| Q2: Can this unit be used for APU starts? |
| A: Yes. It has 150% for 60 seconds and 200% for 30 seconds. That’s enough for any APU start on a narrow‑body or midsize wide‑body. |
| Q3: Does it replace a diesel GPU? |
| A: No, it’s electric. You plug it into the grid. If you need a battery‑powered or diesel GPU, we offer those too – ask sales. |
| Q4: What’s the lead time from Xi’an? |
| A: Usually 4‑5 weeks. We keep a few in stock. Ask before ordering. |
| Q5: Can I get a trailer‑mounted version? |
| A: Yes. Order the -T suffix. Adds a towable chassis with lights, brakes, and pneumatic tires. |
