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 upto 290 V, by a simple transformer action. Three such Variable Autotransformer 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 upto 470 V.

Variable Auto Transformer, manufactured by Purevolt 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.

Variable Auto Transformer, manufactured by Purevolt is the most useful and effective device for continous control of AC voltage.
