“Xinchangda delivered a 5 kW dual winding transformer in 12 days, saving us $12,400 versus our previous supplier. Voltage stability improved by 0.2%.” – James L., Operations Manager, MedTech USA
“The OEM design team understood our niche requirement for low‑EMI in aerospace applications—resulted in a 37% reduction in shielding costs.” – Sara K., Senior Engineer, AeroDynamics Inc.
Certificates: CE, UL, FCC, RoHS, ISO 9001, VDE, CB, GS, SAA.
View Full Certification PackA dual winding transformer has two independent windings on a single core, allowing separate voltage regulation for primary and secondary circuits. It is common in medical equipment, renewable‑energy inverters, and industrial control systems.
Yes. Our R&D engineers work with you to define winding ratios, core material, shielding, and IP rating. Prototypes are delivered within 7‑10 days for approval.
Standard stock (≤5 kW) ships in 10‑15 business days after order confirmation. For custom designs, the typical production cycle is 3‑4 weeks.
All dual winding transformers are manufactured under ISO 9001 and shipped with CE, UL, RoHS, FCC, and VDE certificates upon request.
We accept T/T (30 % deposit, 70 % before shipment), L/C at sight, and PayPal for sample orders. Credit terms (Net 30) are available for qualified accounts.
Yes. Our after‑sales team provides 24 h email support, on‑site troubleshooting (US‑based), and a 12‑month warranty covering material defects.
Limited‑time offer: Free engineering sample (up to 2 kW) + 100% money‑back guarantee if performance criteria are not met.
