By changing the position of the contact position of the brush and the polished surface of the ring-shaped winding to change the turns ratio of the primary and secondary windings, the regulator that finally achieves the main purpose is called a ring regulator. Ring contact type electric voltage regulator is a large contact type electric voltage regulator, which is a replacement product of inductive voltage regulator. Appearance, weight, volume, efficiency, waveform, operation, installation and maintenance are better than the same power induction voltage regulator. Suitable for industrial and mining power, hospitals, national defense, scientific research and other departments as a continuously adjustable test power supply.
