Vertical Roller Contact Variac (SL)

Radio Electric is a reputed manufacturer and supplier of variacs over the past two decades, with many reputed OE customers who consider these as `top of the line?. The company offers radiotone vertical roller contact variacs (Single Layer). These are available in range: oil cooled application ? 60 A single phase, 60 A 3-phase, +/- type, 100 A single phase, and 100 A 3-phase +/- type. Models can be paralleled to achieve higher output current of 120 A, 180 A, and 200 A. This product designed using special strip winding technique, which reduces the length of the column drastically. A double carbon assembly can be provided to give two outputs 180?out of phase (+ve and -ve type), thus reducing the current rating for the variac. For higher current requirement these columns can be parallel. This product is widely used in applications such as plating rectifiers, high power testing equipment, automatic voltage regulator (servo stabilisers), etc.
