Autotransformers

Space-saving autotransformers from TRAMAG

Transformers without galvanic isolation

Autotransformers have only one coil and therefore no galvanic isolation between the primary and secondary circuit. In contrast to a transformers with two independent windings, a lower current flows here.

Compared to TRAMAG mains transformers, our autotransformers have a much more compact design and are therefore suitable for use in environments with limited space.

We provide autotransformers for the following industries
