Frequently Asked Questions

What are the advantages of a toroidal core over a traditional square core?

Toroidal transformers offer higher efficiency, lower electromagnetic interference (EMI), and a more compact size with reduced weight compared to traditional EI transformers.

Can you customize the input and output voltage?

Yes, we can design appropriate products according to specific requirements, including installation dimensions, input/output voltage, and power ratings.

What materials are used in the windings?

We use 100% high-quality copper core for all our toroidal transformers to ensure maximum conductivity and durability.

Are these transformers suitable for outdoor use?

We offer a specific range of waterproof outdoor toroidal transformers (105VA-1000VA) designed to withstand external environments.

What safety certifications do your products have?

Our products meet international safety standards and have obtained ISO9001:2015, CE, UL, TUV, and CQC approvals.

How is the quality of the transformers tested?

Every unit undergoes a rigorous 9-step testing process, including Hi-pot tests, load tests, temperature rise tests, and DC resistance tests before shipping.
