Reliable isolation transformers
for energy applications
Tufvassons have a wide range of transformers and over fifty years’ experience of
making them ourselves. We offer supreme quality isolation transformers for
permanent installation, installation on DIN rails and movable variants that are
connected by a mains lead. You can choose the product yourself, or ask our personnel
to guide you to the right power supply.
Optimum isolation and safe SELV,
suits all environments
The transformer has been developed and adapted for general
use where SELV voltage is stipulated. It provides the correct
protective low voltage, 24V, and thereby guarantees the
maximum possible safety. 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. Installation is easy: The transformer is
connected to an ordinary wall socket, and 24V is connected to
a terminal and secured with strain relief.
