    Description

    stabilizzatore trifase

    Servo Controlled voltage stabilizer is made up of toroidal transformer (variable transformer), BUCK-BOOST transformer and electronic circuits that control the variable transformer rotation, thus adjusting output voltage.

    With the control system which includes fast response time, high starting torque dc engine, it regulates the small voltage changes at the beginning very fast. Servo-engine, is put out of service by limit-switches when it is out of its working limits, and it is put out of service by control circuit when output voltage is automatically adjusted to the set value. When the regulation is complete the energy of the engine is cut by the help of electronic braking circuit and it works silently.
