    • STERCO product line includes variable transformers, the most versatile and reliable voltage controls available, Variable transformers have many industrial and laboratory applications as basic components to control voltage, current, power, heat, speed, light, and electromechanical force. A basic Variable Transformer consists of a single layer, magnet wire winding on a toroidal core of laminated silicon steel. A carbon brush, connected to an output lead, is rotated over a precision ground, plated commutator track 10 tap off voltage at any turn from zero to the maximum output voltage of the winding.   EFFICIENCY & DISTORTION LESS VOLTAGE CONTROLIn contrast to inefficient, wattage-burning resistive-type controllers such as rheostats, Stereo Variable Transformers have an extremely low power loss and efficiencies as high as 98%. Stereo Variable Transformers deliver any desired voltage (within the transformer rating) with negligible variation in output voltage from no-load to full-load current. It produce an accurate transfer of input wave to output circuit, providing distortion less voltage control (a requisite of many sophisticated electronic applications).PLATED COMMUTATOR SURFACEThe commutator surface of each coil is specially plated with precious metal, giving Stereo commutators longer life, increased resistance to corrosion and the capacity to withstand greater overloads (while maintaining a constant contact voltage drop).LONGER LIFE WITH NEGLIGIBLE MAINTENANCEPrecise design assembly of the brush provides excellent mechanical performance, long life, and low-driving torque. Brush replacement is seldom needed and it can be easily replaced, if required. Due to high safety margins of voltage, current-carrying capacity and dielectric strength, longer life of the unit can be expected.RUGGED MECHANICAL CONSTRUCTIONSterco Variable Transformers are precision built to exacting mechanical tolerances using the finest materials available. Quality assurance inspections are performed to insure that the high designed in quality is maintained throughout the manufacturing cycle. A Stereo Variable Transformer provides accurate, reliable and lasting voltage control for a broad variety of applications.

    We are endowed with a state-of-the-art infrastructural facility which back us in manufacturing and supplying 3 Phase Variable Auto Transformer. We manufacture this transformer using high quality materials and components, sourced from authentic vendors. It is an energy saving electrical transformer which can convert the voltage as required. Available in different sizes and technical specifications, our 3 Phase Variable Auto Transformer is highly demanded in the market. We offer this transformer at cost effective prices to clients. Key Features: This transformer has strong mechanical strength and short-circuit withstand ability Has a single layer winding on a toroidal core of high grade steel Ideal for over and under voltage testing of electrical and electronic equipment Description: Continously Variable Voltage Auto Transformer is the most effective device for stepless, breakless & continous control of AC voltage & therefore for various parameters, dependent on AC voltage. These Variable Voltage Auto Transformers, consists of a single layer winding on a toroidal silicon-steel core. As the control knob is rotated, a carbon brush traverses the winding, tapping off a portion of the total voltage across the winding. The brush is in continous contact with the winding. The discrete voltage increments obtained as the knob is rotated are always less than the voltage between turns. Since the brush spans more than one turn, the change in voltage is practically continuous. As output voltage is continously variable, Variable Voltage Auto Transformers are rated in terms of current that can be drawn from the output. The basic Continously Variable Voltage Auto Transformers is meant for operation from a nominal input voltage of 240 V I ph AC & can give output voltage anywhere between 0 to 240 v or 0 to 270V AC by simple transformer action. Three such Variable Voltage Auto Transformers connected electrically in star and mechanically in tandem, become suitable for operation from a nominal input voltage of 415V 3Ph AC and can give output anywhere between 0 to 415V or 0 to 470V. Rating Available: 4 Amps- 1600 Amps

    We are manufacturer and exporter of continuously variable Auto Transformers, Variacs and Dimmer stat which operates on a nominal voltage of 240 V A.C & can give output voltage anywhere between 0 – 270 V, by a simple transformer action. The basic Auto Transformer is meant for operation off a nominal voltage of 240 V A.C & can give output voltage anywhere between 0 – 240 V or up to 270 V, by a simple transformer action. Three such Variable Auto transformer when connected electrically in star & mechanically in tandem, became suitable for operations of 415 V 3 Phase A.C. supply & to give output of 0 – 415 V or up to 470 V. Variacs or variable auto transformer is a continuously variable voltage transformer, having a single layer winding on a toroidal core of high grade Steel. In an autotransformer portions of the same winding act as both the primary and secondary winding. the winding has at least three taps where electrical connections are made. One end of the winding is usually connected in common to both the voltage source and the electrical load. The other end of the source and load are connected to taps along the winding. Different taps on the winding correspond to different voltages, measured from the common end. On one face of the copped winding, along the periphery, a special durable contact surface is made. A specially designed carbon brush slides smoothly on the surface. A contact arm holding the contact brush is fitted to the central shaft and as the control knob is rotated, the carbon brush slides over the winding and taps off a portion of voltage across the winding. Any desired voltage within the maximum range can be obtained by adjusting the position of the brush. The calibrated dial reads approximately the output voltage at no-load, when the input is at its rated value. Rotation of the brush arm by manual of motor drive delivers an output voltage from zero to or above line voltage. Variable Auto Transformer, manufactured by EnergX is the most useful and effective device for step less, break less and continuous control of A.C voltage and therefore, for control of various other parameters, dependent on A.C voltage. It is ideal controlling device for numerous applications in laboratories and in industrial & commercial fields.

This is very important for proper collection of current by the carbon brushes thus reducing the heat generated. Our standard coils are 100 Amp, 150 Amp, 200 Amp. Using these coils we manufacture oil-cooled variautos from 100 Amp 3 Ph to 1200 Amp 3 Ph capacity (415 V input and 0-470 V variable output). In high current rated models we use multiple coils with properly rated balancing coils to achieve the rated current. Based on the calculations of cooling area appropriate no. of radiators &fins  are used. These variautos are generally motorized with geared mechanism. We also cater to tailor-made requirements.
