Leakage transformer RUT 500



In railway applications, where it‘s about the greatest possible comfort and safety of passengers, components are required that save space, are safe and have a long service life. Supply interruptions or voltage drops can lead to a range of undesirable effects such as the loss of motor power.

The REO leakage transformer ensures harmonized current and voltage outputs, filtering harmonics, and limiting the ripple current.With the spatial separation of the primary and secondary windings and the resulting intentional increase in the magnetic leakage field, the REO leakage transformer achieves a loose magnetic coupling.

This results in the combination of the function of a transformer (transforming voltage with galvanic separation) and a current-limiting choke.
