Double regulation power supplies include: DO series, AxN series, ATR series.

The Power Supplies of the AxN series are built with the double regulation technique. The first regulation is obtained by the partialization of the grid circulation angle as automatic variac. The second regulation functions as a linear stabilizer with constant dissipated power. As a result, this solution allows to obtain both low power dissipation and, thanks to the linear regulation, excellent output characteristics.

DO series Power Supplies are made with the double regulation technique. A linear stabilization circuit is added to a thyristor-controlled bridge, which allows to reduce the power absorbed by the network. This type of control allows a volume reduction compared to linear power supplies but it preserves the characteristics of low noise and speed of response.

ATR linear Power Supplies series are built with the double regulation technique. the first regulation  is obtained by the personalization of the grid circulation angle as automatic variac. The second regulation functions as a linear stabilizer with constant dissipated power. As a result, this solutions allows to obtain both low power dissipation and, thanks to the linear regulation, excellent output characteristics.
