Why Your DC‑DC Projects Fail Without the Right Transformer

High Losses & Over‑Heating: Inefficient cores can raise system temperature by 30 % → additional cooling cost.
Unstable Output Voltage: Poor winding tolerance leads to ±5 % ripple, causing firmware resets.
Long Lead Times: Generic off‑the‑shelf parts often require 8‑12 weeks, delaying product launch.
Regulatory Risks: Non‑CE/UL‑listed transformers can block customs clearance in the USA.
Cost Overruns: Over‑spec’ed or under‑spec’ed units force redesigns, adding 12‑20 % to project budget.

Customer Testimonials & Certifications

John M., Senior Procurement Manager, VoltTech USA – “Xinchangda delivered a 120 W DC‑DC transformer 30 % cheaper than our previous supplier. Efficiency rose from 88 % to 94 % and we launched two weeks ahead of schedule.”
Emily S., VP of Engineering, GreenEnergy Europe – “The custom low‑noise design met our FCC Part 15 limits without extra shielding. ROI was realized within 3 months.”
Mark L., Operations Director, MedEquip Inc. – “ISO 13485 and CE certification were ready on day 1. No customs delays, and the units passed all thermal cycling tests.”

All products are backed by: CE, UL, FCC, RoHS, VDE, CB, ISO 9001, ISO 13485 certificates.

Frequently Asked Questions

What is the typical lead time for a custom DC‑DC transformer?

Standard prototypes are ready in 5‑7 business days; bulk production starts within 14 days after artwork approval.

Can you provide UL‑listed transformers for the US market?

Yes. All our US‑bound units carry UL 60950‑1 and UL 61000‑4‑3 compliance, with full test reports available on request.

Do you offer low‑volume OEM runs for startups?

Minimum order is 500 pcs for custom designs; we also provide “pilot‑run” services (as low as 100 pcs) with the same quality standards.
