Variable Auto Transformer Auto Variable Transformers can be used specifically for Servo voltage stabilizer, rectifier unit, battery chargers, DC motor drives, electroplating equipments, high voltage test benches etc. This transformer is a constantly variable voltage auto transformer, having a changeable carbon tip, set to a brush arm sliding on a silver plated commutator. Revolution of the brush arm either by manual or by motor drive, distribute an output voltage from zero to or above line voltage. Our product has some salient features like :
Hassle free and maintenance free
Highly efficient, have the capacity to bear over load
Even and Linear Output
