We are widely acclaimed for offering a durable range of Variable AC Transformer, commonly known as Variacs. Our Variable AC Transformer is used to provide a voltage-adjustable source of AC electricity. The core of the Variable AC Transformer is made of high grade, non aging continuous CRGO strip and carefully annealed that results in low magnetizing current and core losses. The output is linear and Variable AC Transformer does not produce any distortion in the wave form. We have designed Variable AC Transformer to withstand heavy overloads of short durations such as starting currents of motors. We are proficient in offering Variable AC Transformer as per the details given by the clients.
