Servo Voltage Stabilizer

HI-Tron Servo Voltage Stabiliser essentially employs a solid-state circuit that 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 voltage and the resultant error signal controls the Servo Motor providing true proportional control systems rather than on/off circuits.
