Safety Transformers

Railway workplaces require an extraordinary care for operating with electro technical products. To maintain the required user protection against electrical hazards, it may be necessary to install safety and insulating transformers

Insulation also eliminates that two defective heating elements create a “Track occupied” signal due to a short between the right and left track. Furthermore, it eliminates problems with potential differences between the public mains and the rail potential.

With the SAN safety transformers you get:
