Safety isolating transformer **PT 7,5/2/9** 

## Advantages 

Minimum size at high output 

Integrated overload protection using PTC in the input Also with dual output voltage for series or parallel connection 

Permanent corrosion protection, high insulation value and maximum electrical reliability thanks to XtraDenseFill resin encapsulation Self-extinguishing potting material 

Space saving installation thanks to additional screw mounting in the base plate 

## Applications 

As a mains transformer for adjustment of the voltage and simple electrical isolation. 

Safety transformer for the safe electrical isolation of the input and output sides. The transformer is suitable for creating SELV and PELV circuits because of the limit on the output voltage.
