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 power supply for environments that set high requirements on
isolation 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.
When there are especially high
requirements for isolation
The transformer is used when there are greater demands on
isolation between mains voltage and safety extra-low voltage
than normal. It fulfils isolation category III (>4kV), has protective
separation between the primary and secondary windings and is
adapted for supplying SELV- and PELV systems. The output
voltage is stable and the transformer is ideal for distribution
boards and standard enclosures with four modules. Naturally,
the product also has short-circuit and overload protection, as
well as complying with the insurance companies' requirement for
self-extinguishing plastic in the housing.
