We are manufacturer and supplier of best quality single phase control transformers from 0.5 VA -100 K VA., which find application for converting alternate current from one voltage to another. These transformers could either be step up or step down voltage. Under normal operating conditions, a transformer is a low continuance, long lasting static solid state device with actually no moving parts. It includes two or more coils of insulated wire that are wound on a laminated steel core. When prime coil receives the incoming voltage, the iron core is magnetized & that induces the voltage in the secondary coil. The actual voltage ratio between prime & secondary coils depends up on the turn ration of both coils.


Our control transformers are incorporated with superior quality insulating materials. This insulation is used to electrically insulate turn to turn windings, layer to layer windings, primary to secondary windings and ground. These control transformers are vacuum impregnated with VT polyester resin and oven-cured, which seals the surface and eliminates moisture. Filling the entire unit provides a strong mechanical bond and offers protection from the environment. These transformers are earth sealed between Primary & Secondary. They also possess tapings on the input side to facilitate selection according to site voltage.

Manufactured as per IS:9815, these GSA servo voltage stabilizers are available in single and three phases and used with sensitive electronic & electrical equipment. These 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.


Our servo voltage stabilizers 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 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, our 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.
