    • 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 variable voltage regulator makes variable voltage supplies from 0-11 kv or any desired voltage upto 5000 kva. These variable voltage supplies are used for special purpose applications and testing. principle of operation : the variable voltage supply regulator consist of following basic components depending on the rating of the equipment. Step up transformerbuck boost transformerrolling contact type voltage regulatorautomatic control gear the variable voltage regulator comes with variable voltage supply regulator with constant input and variable output. It consists of a step up transformer, regulators and buck boost transformer. This circuit is normally used to vary on load voltage when the regulator used in conjunction with buckboost transformer and step up transformer. the equipment is available with following control devices : manual version motorized version remote control in manual version a hand wheel t handle is provided and desired output voltage can be obtained by rotating the wheel handle manually.in case of motorized version and servo motor will be provided which can be operated by two sets of push buttons or toggle switch for raising and lowering the output voltage. In case of remote control arrangement, one extra set of push buttons will be provided in your main panel from where the operator would be able to maintain the desired voltage with the help of those push buttons. description : rolling contact regulator : this is essential a continuously tapped auto wound transformer having helical coils mounted on a conventional laminated transformer core. However, the regulating winding is designed as a single layer type giving longer and slimmer version of the transformer coil but in principal it is the same. the regulating winding is varnished and baked to improve rigidity and ensure that the construction is non-hydroscopic. After proper treatment longitudinaltrack is ground on the coil to form a bared copper surface with the winding wire-covering providing inter turn insulation. Graphite rollers, assembled on carrier boards, traverse throughout the length of the coil track. These rollers are connected electrically with the output terminals and as they are driven over the track, a variable voltage is obtained. the regulator may be of one sided or can be made double sided. In case of double sided regulator both side of regulating winding is bared and allows rollers to be driven in opposite direction on either side of the coil. In such cases carrier boards are provided on both sided of the coils and the output terminals will be taken out though balancing transformer. the contact carrier is driven by a hand wheel t handle or motor, which is coupled, to the chain drive. Limit switches operated by the carrier board are fitted to prevent over run. In case of your specific requirement, additional limit switches will be fitted for minimum position inter-locking along with the auxiliary circuit. The power supply of the motor is derived from the regulator unless otherwise specified. The entire regulator assembly is housed inside a rigid m.s.tank filled with oil. The hand wheel t handle, motor push buttons etc. Is fixed up inside a separate sheet steel box, which is attached to the main tank. Wherever automatic control is required, the solid stat voltage-sensing relay is also provided inside a sheet steel box fitted along with the regulator tank. for voltage regulating units, the equipment consists of regulator and transformer as explained earlier. The description of the regulator has been already described above. The step up and buck boost transformer will be of conventional type as per is:1180 or is:2026 in voltage regulating un

    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.
