Power supply single phase autotransformers are realised according to the European legislation EN 61558-1 and CEI 96-3, to the American legislation UL 506 and UL 1585 and to the Canadian legislation CSA 22.2 n66 in order to be used in the electromechanical and electronic industry and electromedical field as well.

The column type refers to the distribution of the windings on two columns. This solution allows the use of magnetic cores (U+I) of reduced section with consequent limitation of the insertion currents and a high heat dissipation surface.

The plus of this products is the reduction of their weight and volume keeping the power unchanged.

The supply voltage must not exceed 1000VAC and 500Hz. The autotransformers are immersed in an insulating liquid and/or tropicalized for a better yield and a better reliability in wet places.

Our products are entirely realised in Italy with first choice raw materials strictly selected in order to guarantee the best quality and safety.

Our Technical Department is qualified and prepared to satisfy all kind of demands including tailor made requests.
