Make secure safety device
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.
Safe power supply
for alarms
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.
