Variable Auto Transformer (Variator)
Variable Auto Transformer, manufactured by BHASIN PACKARD 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. BHASIN PACKARD offer auto variable transformers with ratings from 120V to 600VAC single and three phase and fractional to 700 Amps.
Variac transformers are AC voltage controls that provide a variable AC voltage. Their distortion free output is ideal for sensitive electronic applications. Variac transformers are available that boost the output voltage in excess of twice the input voltage. Input frequencies up to 2 KHz can be easily accommodated.
