YY-D-250 Series
With synchronous rectification technology, conduction loss is significantly reduced, improving efficiency while generating less heat.
Eliminates signal distortion or equipment malfunction caused by electromagnetic interference (EMI).
Low ripple and low noise deliver pure, stable output. Even when powering precision sensors or high-end test equipment, the signal remains interference-free, ensuring accurate data and system stability.
- Output Power: 250W
