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. The connection glands are specially
designed to fit tightly round the cable. 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.
