YY-D-400 Series
Using synchronous rectification technology significantly reduces conduction losses, improving efficiency with less heat generation.
A temperature-controlled adaptive fan intelligently adjusts speed and start/stop to maximize fan lifespan.
Eliminates signal distortion or equipment malfunction caused by electromagnetic interference (EMI).
Low ripple and low noise ensure a clean, stable output; even when powering precision sensors or high-end testing equipment, signals remain free from interference, data remains accurate, and the system stays stable.
- Output Power: 400W
