Adapted to your needs
Tufvassons have a wide range of transformers and over fifty years’ experience
of making them ourselves. Within the Testing area we develop power supply for
testing equipment. It might, for example, be a rotary transformer for internal
installation, as well as sealed versions for laboratory use. We are not satisfied
until we have developed a product that meets all the requirements set by your
testing equipment.
1-phase rotary transformer
for testing equipment
The transformer is called an autotransformer, which means
that it doesn’t have separate windings. The winding
consists of double-varnished wire mounted on a robust
frame together with a carbon brush. The transformer
enables stepless voltage control with retained sine shape. It
is highly efficient and electromagnetic interference is
completely avoided. Just like other products from
Tufvassons, the transformer is easy to install, in this case
assembly on a table is recommended.
