“Switching to Xinchangda’s step‑up transformers cut our voltage‑fluctuation incidents by 37% and saved $120k annually.”
All products comply with CE, FCC, RoHS, ISO 9001, and VDE certifications. Full documentation is available on request.
A step‑up transformer increases voltage by having more turns on the secondary winding than on the primary. According to Faraday’s law, the induced voltage is proportional to the turn ratio (Vs/Vp = Ns/Np). This allows low‑voltage input to be transformed into a higher‑voltage output while conserving power (neglecting losses).
Determine the required output voltage and the available supply voltage. The ratio is calculated as Vs/Vp. For safety margins, add 5‑10% to the calculated ratio and verify with the load’s current demand and insulation class.
Yes. Our R&D team can tailor turn count, wire gauge, enamel type, and housing material (metal, epoxy, or UL‑rated enclosures). Lead time for standard OEM orders is 7 days; for complex ODM projects, 14‑21 days.
We ship worldwide via DHL, FedEx, or ocean freight. Standard payment: 30% T/T upfront, 70% before shipment. For trusted partners, we accept L/C, PayPal, or net‑30 terms.
We provide a 24‑month warranty, free technical consultation, and on‑site troubleshooting within 48 hours for critical failures. Documentation includes test reports, CE‑DoC, and a lifetime replacement policy for defective windings.
