Buy toroidal transformers

Toroidal transformers are particularly powerful transformers with a circular, closed core made of ferromagnetic material. Thanks to this design, they enable efficient voltage conversion with minimal losses and electromagnetic interference. Compared to conventional E-I transformers, they impress with their high energy efficiency, compact size and reduced magnetic field.

The transformers are available in different power levels, voltage ranges and winding types. This makes them suitable for demanding applications in electronics and industry. Their high efficiency and low leakage losses make them the ideal choice for numerous industries.

Toroidal transformers are used in industrial electronics, medical technology and audio technology, among other things. They ensure a stable power supply and reduce interference in signal transmission, especially in hi-fi amplifiers. They are also popular in control cabinets, measuring instruments and power supplies because they hardly heat up and operate almost silently.
