    • 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 Spectron Continuously Variable Voltage Auto Transformer is meant for operation of a nominal voltage of 240V AC and can give output voltage anywhere between 0 tp 240V, or upto V by a simple transformer action. Three such Spectron Continuously Variable Voltage Auto Transformer when connected electrically in star, and mechanically in tandem, become suitable for operation off 415V 3 Phase AC supply and to give output from 0 to 415 V or up to 470V.

    Single Phase High Current Air Cooled Variable Autotransformers each of 200A rating (Radiotone make) We specialize in the manufacturing of Single Phase High Current Air Cooled Variable Autotransformer (colloquially known as Variac) in 100A /200A /400A /600A /800A /1200A ratings. Three Phase units are built by using such three stacks & motorizing them on common shaft. This is a substitute for oil cooled units which are less preferred, for safety reasons, in many hazardous applications. Single Phase High Current Air Cooled Variable Autotransformers (colloquially known as Variac) are very easy to maintain & service. Enclosed units are also available.
