High Quality, High Performance Toroidal Power Transformers and Inductors

Engineers in a broad range of industries have discovered the performance advantages of our toroidal power transformers.  Our transformers are used in a variety of industries: medical electronics, test and measurement systems, industrial control panels, data communications, motor controls, light fixtures, audio systems, robotics, UPS, and avionics.

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.
