Transformers suit noise-sensitive equipment

Shilchar's R-core transformers are manufactured using a novel rectangular core with a round cross-section, and are available with ratings up to 1200VA.

Shilchar's R-core transformers are manufactured using a novel rectangular core with a round cross-section, and are available with ratings up to 1200VA.

The novel feature of the transformer is that the core is gapless and continuous.

The winding is performed on special round bobbins on two parallel legs of the core.

In comparison with EI transformers of same capacity, the R-core transformer is compact (nearly 40% smaller) and has a low temperature elevation.

Further, the leakage flux of the transformer is very low (about one-tenth of a conventional transformers) which permits the equipment manufacturer to place the transformer closer to critical electronic components.

The balanced winding and low leakage flux ensures low noise.

This makes the transformers ideal for use in medical equipment, audio and video amplifiers and other noise-sensitive equipment.

The other unique feature is the use of two-part bobbins.

The primary and secondary windings are made on separate bobbins, thus ensuring complete isolation between the two windings and ensuring compliance with safety standards.

The R-core transformers have found wide application in CRT display units, audio equipment, satellite receivers, biomedical equipment, printers, photocopier machines, weighing scales and many more.

Devices are available from MRC Components.
