Precision-engineered thyristorised power controllers for furnace heating, automation, and reliable industrial thermal control.
Sudarshan Electronics specializes in manufacturing thyristorised Industrial AC Power Controllers engineered for furnace heating and process automation. Founded in Bengaluru with a commitment to proving that Indian engineering can compete with the best in the world, we design and build every controller in-house around precise firing control and long service life. From single phase 15A units to three phase systems rated up to 3000A, our controllers deliver the stable, repeatable, and precise thermal control essential for furnaces, kilns, extruders, and moulding lines. Each unit is fully load-tested before dispatch, so commissioning is predictable and downtime stays minimal. The result is reliable, energy-efficient and precision power control trusted by industries across multiple sectors for more than three decades.
