All units ship with CE, UL, RoHS, FCC, CB, GS, VDE, SAA, ISO 9001, and where applicable, FDA or GMP documentation. Full test reports are attached to every order.
Frequently Asked Questions
What is the typical lead time for a custom power transformer?
Standard stock items ship within 2 weeks. Custom designs (voltage, kVA, tap‑changer) are typically completed in 4 weeks after final design approval.
Can you provide UL and CE certificates for US imports?
Yes. Every batch includes UL‑listed and CE‑marked test reports, plus a Declaration of Conformity (DoC) that satisfies FDA, FCC, and REACH requirements.
Do you offer OEM/ODM design services?
Absolutely. Our 10 R&D engineers can develop schematics, 3‑D models, and prototype units based on your electrical and mechanical drawings.
What payment terms are accepted?
We accept T/T (30 % advance, 70 % before shipment), LC at sight, and PayPal for samples. Credit terms (Net 60) are negotiable for established accounts.
How do you handle after‑sales service?
A dedicated after‑sales engineer is assigned to each client. We provide on‑site troubleshooting, warranty replacement within 12 months, and a 24 / 7 support hotline.
Limited‑Time Offer: 5 % Discount on First Order + Free Engineering Sample
Order before May 31, 2026 and enjoy risk‑free sampling, no minimum order quantity, and a 30‑day money‑back guarantee if specifications do not meet your design.
Tom Reynolds, Senior Purchasing Manager, GreenTech Energy
“The transformer arrived on schedule, fully certified, and performed 8 % better than the spec sheet. We saved $45k on our next phase thanks to the lower price and faster lead time.”
Linda Park, Operations Director, Nova Medical Devices
“Xinchangda’s OEM service let us integrate a custom cooling circuit without redesigning the enclosure. Their engineering support was available 24/7.”
Mark Chen, Supply Chain Lead, Titan Manufacturing
“The transparent pricing and ISO‑9001 audit package eliminated our compliance worries. We placed a repeat order within two weeks.”
