subject: Servo Voltage stabilizer Manufacturer [print this page] STABILINE Servo Voltage Stabilizer essentially employs a solid state circuit which controls the Servo Motor. The motor is mechanically coupled to the arm of a transformer which feeds to the primary of a series control buck-boost transformer.The stabilizer output voltage is compared with the reference volatge and the resultant error signal controls the Servo Motor providing the proportional control systems rather then on/off circuits.
