    • 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.

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.
