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.
