Power your next generation of isolated power supplies with Xinchangda’s transformer for flyback converter. Designed for OEM and ODM projects, our units deliver up to 95% efficiency, tight tolerance, and rapid 2‑week delivery—exactly what US purchasing managers need to stay ahead of cost and schedule pressures.
Most US suppliers charge a 30‑40% premium for flyback transformers, inflating BOMs and eroding margins. Our pricing is 25% lower thanks to a 5000 m² factory and 14 fully‑automated production lines.
Low‑cost imports often fail to meet IEC/UL standards, leading to field failures and costly warranty claims. Xinchangda holds ISO 9001, CE, FCC, RoHS, and VDE certifications, guaranteeing repeatable performance.
Typical lead times exceed 45 days, while technical support is limited to generic email replies. Our 2‑week standard delivery and 24/7 engineering hotline cut time‑to‑market dramatically.
