Custom built transformers

In addition to our standard ranges throughout our website we are pleased to quote for your special requirements and build your custom transformers.

The transformers in this range have been built to customers requirements and therefore do not make up part of our standard ranges. For this reason, a transformer purchased from the custom range that has not been specifically designed for you cannot be returned if it is unsuitable for your purposes.
If you are ordering from this page be very sure you are ordering exactly what you need.
This does not affect our warranty offer for any faulty or failing unit.

As manufactures we pride ourselves on using only the best British steel, a rigorous testing regime and putting our customer first.

We are known for punctual delivery of ordered custom transformers and can cater to almost any specifications of toroidal transformers.

Engineers in a broad range of industries have discovered the performance advantages of our toroidal power transformers.

Our transformers are used in 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.

Contact us today with your query and and let us build your perfect custom transformer.
