    Description

    stabilizzatori monofase

    VSR Servo Controlled voltage stabilizers use a toroidal transformer (variable transformer), a BUCK-BOOST transformer and an electronic circuit that controls 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 very fast. Servo-motor 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 motor is cut by the help of electronic breaking circuit and it works silently.
