“Switching to Xinchangda’s toroidal transformers cut our component cost by 32 % and eliminated the hum issue that delayed our product launch. Delivery was exactly 48 hours after PO.” – John M., Procurement Manager, MedTech Corp.
Our factories hold the following certifications, guaranteeing compliance with U.S. and EU regulations:
Price is based on power rating, voltage class, material (copper vs. aluminum windings), custom shielding, testing level (standard vs. IEC 61800‑5‑2), order quantity, and shipping method.
Yes. Submit a short RFQ (minimum 500 units) and we’ll email a detailed price list within 24 hours, including FOB Shenzhen and DAP (Delivered at Place) U.S. rates.
Our R&D team (10 engineers) can co‑design transformers to meet ≤30 dB noise, ≥98 % efficiency, and any IEC/UL safety standard. No extra NRE fee for orders over 2 k units.
Standard production takes 3 days; after QA, we arrange air‑freight. Most customers receive the first batch within 48 hours of PO confirmation.
All units come with a 12‑month warranty, free replacement for any manufacturing defect, and 24/7 technical hotline (English, Mandarin, Spanish). Remote testing assistance is provided via video conference.
