GSA Industries manufactures Servo Voltage Stabilizer. GSA Industries is an ISO 9001-2000 certified company offering Servo Voltage Stabilizer with Frequency 47 - 53 Hz which is available in single and three phases and is used with sensitive electronic & electrical equipment. These Servo Voltage stabilizers are mainly used to protect the electrical & electronic equipments, which are effected by the fluctuation in input mains supply and do not operate when not used at the specified voltage. They save the life of costlier appliances, CNC machines, electrical equipment, medical equipment, motors lab equipment etc. Through connecting AC voltage which is not stabilized, and dips at one point of time and at other point of time rises to very high value. The principle of operating Servo Voltage Stabilizer involves comparing the output voltage with built in stable reference voltage source. The solid state control circuit operates the motor whenever the output voltage falls or rises beyond the preset voltage. Precisely engineered to perfection, servo voltage stabilizer features 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 & resultant error signal controls the Servo Motor providing true proportional control systems rather than on/ off circuits.
