Toroidal Transformers

Trans-Tronic have designed and manufactured Toroidal Transformers for nearly 40 years but in 2008 we acquired the Antrim Transformer business which brought with it a range of standard products which are approved by UL (Underwriters Laboratories) and KEMA KEUR (Dekra approval body).

We are able to produce Toroidal Transformers up tp 5kVA but our standard range of UL and KEMA approved products are from 15VA to 1kVA.

We manufacture a range of medical isolation transformers.

Our Audio Toroidal Transformers are manufactured with a low flux density for low noise and you can add a goss band for screening purposes. We specialise in manufacturing high quality Toroidal Transformers for valve amplifiers.


Our standard fixing comprises of 2 rubber pads, a metal clamp plate and an appropriate nut and bolt.

Alternatively the centre of the toroid can be filled with resin and drilled to enable fixing.
