Welcome to Variac Transformers** Catalog


We offer Variac transformers (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 to 2000 Hz can be easily accommodated.
