The Real Pain Points for Purchasing Managers

High Unit Cost: Conventional EI‑type transformers often carry a 20‑30 % price premium for the same power rating.
Quality Inconsistency: Variable winding tolerances lead to overheating and premature failure, causing costly downtime.
Long Lead Times: Overseas suppliers can take 30‑45 days, jeopardizing project schedules.
Regulatory Barriers: Missing CE, UL, or RoHS certifications forces re‑testing and delays market entry.
Limited Customization: Off‑the‑shelf designs rarely meet specific voltage‑step ratios or mounting constraints.

Result: Your ROI erodes, product launches slip, and after‑sales support becomes a nightmare.

Frequently Asked Questions

What is the typical lead time for a custom step‑up toroidal transformer?

Standard lead time is 7 business days after artwork approval. For large‑volume orders (≥10 k units) we can ship within 5 days using our 14 automated lines.

Can you provide UL and CE certification for a US purchase?

Yes. All our step‑down and step‑up toroidal transformers are manufactured under ISO 9001 and undergo UL 60950‑1 and CE IEC 61869 testing before shipment.

Low Power Transformer

Do you offer sample units before a bulk order?

We provide a free engineering sample (up to 5 W) and a paid functional sample (up to 100 W) with freight prepaid for US customers.

What payment terms are accepted for first‑time overseas buyers?

We accept T/T 30 % deposit, 70 % balance before shipment, or L/C at sight. For qualified partners, we can arrange net‑30 days after the first order.

How do you handle after‑sales service and warranty?
