“Switching to Xinchangda’s push‑pull toroidal transformer cut our device‑level power loss by 18 % and saved $45 k in the first quarter. Delivery was exactly 14 days – on‑time, every time.”
Linda S., Operations Manager – GreenEnergy Solutions
“The custom winding we requested met our UL‑listing deadline two weeks ahead of schedule. The product passed all FCC tests on the first try.”
Certificates: CE, FCC, RoHS, ISO 9001, UL, GS, CB, VDE, SAA – all visible on our factory page.
Yes. Our R&D team (10 engineers) can design winding ratios, voltage ratings, and enclosure materials to meet IEC 61800‑3 or FDA‑class requirements. Lead time for a 1,000‑unit run is 14 days after design approval.
All units are CE, FCC Part 15, UL‑listed, RoHS compliant, and ISO 9001‑certified. Additional certifications (e.g., IECEx) are available on request.
Our 5,000 ㎡ factory runs 14 fully automated lines, achieving economies of scale that lower unit cost by ~12 % versus typical Chinese suppliers, while ISO 9001 processes guarantee consistent quality.
Standard terms: 30 % T/T deposit, 70 % before shipment. We support L/C, PayPal, and Stripe for smaller orders. Air freight is $2.8/kg; sea freight is $0.45/kg with door‑to‑door service.
Yes. A dedicated support line (24 h) and a 12‑month warranty are included. Remote troubleshooting and firmware updates are offered at no extra cost.
Limited‑Time Offer: Order before May 31 2026 and receive a **FREE engineering sample** plus **30 % off** the first 500 units.
