We manufacture precisely engineered servo voltage stabilizer which essentially has a solid state circuit to control the servo motor. The motor is mechanically attached to the arm of a continuously variable auto transformer which feeds to the primary of a series control buck-boost transformer. The stabilizer output voltage is compared with the reference voltage and the resultant error signal controls the Servo Motor providing true proportional control systems rather than on/ off circuits.
