R-core Transformers
R-core Transformers
R-core Transformers are manufactured using the unique rectangular core with round cross section known as r-cores. The special feature of this transformer is that the core is gap less and continuous. The winding is done on special round bobbins on two parallel legs of the core. In comparison with EI transformers of same capacity, the r-cores transformer is compact (nearly 40% smaller) and has a low temperature elevation further the leakage flux of the transformer is very low (about 1/10th of conventional transformers) which permits the equipment manufacturer to place the transformer close to critical electronic components. The balanced winding & low leakage flux ensures low noise of the transformers. This gives a cutting edge to the transformer for use in medical equipment, audio & video amplifiers & other noise sensitive equipment. the other unique feature is the use of bobbins in two parts. The primary winding and secondary winding are done on separate bobbins thus ensuring complete isolation between the two windings. This allows meeting of any safety standards requirement. the r-core transformers have found wide application in CRT display units, audio equipments, satellite receivers, bio-medical equipment, printers, photo-copier machines, weighing scales and many more.
