Close Type Variac • Feature of close type variac • Silver plated commutator • Brush arm • Movable carbon tip • Excellent in two phase electric supply • Rigid construction, lateral technologies • Designed for voltage correction in electric power network and circuitry • Highly user-friendly www.apexelectricals.in

9. Oil Cooled Variac • Features of Oil Cooled Variac • 3 phase 415 volts output • Skilled in three phase electric supply • Starts with the basic units of 40AMPS rating • Commendable voltage regulation www.apexelectricals.in

10. Air Cooled Variac • Features of Air Cooled Variac • Save your power • Promises 98% efficiency • Easily available in both Single and Three Phase models up to 300 Kva • Delivers excellent performance • Offers digital output facility www.apexelectricals.in

11. Advantage of Variac Transformer • Saving in size and weight. • Size is very smaller. • Voltage regulation is much better. • Cost is low. • Excitation current requirement is low. • In conventional transformer step up and step down voltage are fixed while in auto transformer output vary as per the requirement www.apexelectricals.in

12. Disadvantage of Variac Transformer • If any winding of auto transformer short circuited the output voltages will swing to higher voltages than operating voltage causing a very huge damage. • It consists of single winding around the iron core which develops • There is no isolation of low and high voltages either at the input or at the output of the transformer. So any noise or voltage pertaining on one side will reflects on the other side. So Filtering circuits are necessary wherever auto transformer is used in electronic circuits. change in voltage from one end to the other. www.apexelectricals.in
