If conventional laminated power transformers aren't performing to your standards, consider our toroidal transformers. With their very low magnetic strayfield emission levels, quiet operation, low weight, small size, high efficiency, and easy assembly, our toroidal power transformers will deliver the superior performance capabilities you require.

We offer the industry's largest selection of
standard design toroidal power transformers for medical and commercial applications. But if these don't exactly fit your needs, then our engineers will design a custom transformer best suited to your requirements.
