The Real‑World Pain Points Stopping Your Projects

High purchase price – Conventional EI‑core transformers often carry a 20‑30% premium due to inefficient design.
Excessive electromagnetic interference (EMI) – Noise that forces costly shielding or redesign of PCBs.
Large footprint – Bulky units limit equipment layout and increase material handling costs.
Long lead times – Overseas suppliers average 45‑60 days, delaying production schedules.
Uncertain compliance – Lack of CE, FCC, or UL certifications can halt product launch in the U.S.

Result: Project overruns, higher OPEX, and missed market windows.

Frequently Asked Questions (FAQ)

What is the typical lead time for a custom toroidal power transformer?

Standard stock models ship in 7‑10 working days. Custom OEM/ODM projects require 15‑25 days after design approval and tooling confirmation.

Can you provide UL or FCC certification for the transformers shipped to the USA?

Yes. All our U.S. shipments are accompanied by UL, FCC, and CE test reports. We also offer on‑site testing if required.

Do you support low‑volume orders for prototyping?

Absolutely. Minimum order quantity (MOQ) for prototype runs starts at 50 pieces, with fast‑track tooling to keep time‑to‑market under 2 weeks.

What payment terms are available for U.S. buyers?

We accept T/T (30 % deposit, 70 % before shipment), L/C at sight, and PayPal for small orders. Credit terms can be negotiated for qualified accounts.

How do you handle after‑sales service and warranty?

All transformers carry a 24‑month warranty covering material and workmanship. Our U.S. support team provides remote diagnostics, spare‑part logistics, and on‑site repair within 48 hours for critical equipment.
