Designed in 1990 the ET-C is the original Mode Electronic Transformer for low voltage lighting and the worlds' first fully dimmable electronic transformer. The clever input circuitry makes it appear as a resistive load and therefore dimmable by any type of leading edge or trailing edge dimmer, including standard UK domestic dimmers.

A high ambient temperature rating, automatic short circuit and overload protection together with the use of first brand parts makes the ET-C a high quality and reliable product with an excellent reputation throughout the industry.

The ET-C transformer uses hand wound components to offer a transformer with near zero levels of audible and electrical noise. This makes it the ideal choice for sensitive projects such as residential installations, theatres, auditoriums, presentation suites and home cinemas.
