A company in the ADDTECH group.
Meets the requirements of the
energy sector
Tufvassons has a wide range of transformers and over fifty years’ experience of
making them ourselves. We offer transformers for environments that set high
requirements on insulation and safety, the energy sector for example. We help you to
make the correct choice, and if you need a product that is not available, we ensure it
is made.
Ideal for
low voltage installations
The transformer is used when there are greater demands on
insulation and safety than normal. It is suitable for voltage feed
in SELV and PELV installations such as monitoring systems,
temperature control, lighting and alarms. It goes without saying
that the transformer also has short circuit and overload
protection, and also complies with the insurance companies'
requirement for self-extinguishing plastic in the housing.
