Our Services
Quality Control
Every unit load tested – 150A for 1 hour, then 200A for 30 seconds. Thermal camera scan.
Ripple checked – At 80A and 150A. Must stay under 0.2V RMS.
Drop test – One from each batch dropped from bench height. Must still run.
Final inspection – Human checks handles, knobs, and connectors.
R&D Results
Weight reduction – First prototype was too heavy. Switched to a high‑frequency design. Cut weight by 40%.
Handle placement – Original handles on the sides were awkward. Moved to the top. Much better.
Fan noise – Early unit had fan running constantly. Too annoying. Now it only spins when hot.
Customer request – Added a shoulder strap option for walking across ramps.

FAQ |
|---|
| Q1: What aircraft can this power? |
| A: Any 28V aircraft that draws less than 150A continuous. That includes most single‑engine pistons (Cessna 172, Piper Archer), light twins (Beechcraft Baron), and small helicopters (Robinson R22/R44, Schweizer 300). For a King Air or PC‑12, you'll need our 300A model. |
| Q2: Can I charge the aircraft battery with it? |
| A: Yes. Set voltage to 28.8V (lead‑acid) or 29.4V (NiCd). Set current limit to 10‑20A. The unit runs in constant‑current mode until the battery reaches set voltage. |
| Q3: Will it run from 110V? |
| A: Yes,The ADCW‑28150's input voltage sport customized. On 110V, max output drops to 100A continuous, still fine for most light aircraft. |
| Q4: How long is the output cable? |
| A: Standard is 3m. We can do 5m or 10m for an extra charge. Longer cables need thicker wire – let us know. |
| Q5: Lead time from Xi'an? |
| A: 2‑3 weeks. We keep a few in stock. Ask sales. |
| Q6: What is a 28V DC rectifier used for in aviation? |
A: It provides stable DC power for aircraft engine start and ground maintenance. |
| Q7: Can it handle engine start surge current? |
A: Yes, it supports up to 400% overload capacity. |
| Q8: Is it compatible with military aircraft standards? |
A: Yes, it complies with MIL-STD-704F. |
