Toroidal transformers



Single-phase toroidal transformers, power range from 20 to 300VA. Designed and tested according to EN61558. Suitable for installation in electronically equipment. Designed as a safety isolating transformer with separate insulated windings and prepared for class II equipment. Short circuit and overload protected with thermal fuse on primary side. Up to 50% less weight than a similar conventional transformer. Low magnetisation currents and no-load losses. Suitable as safety isolating transformer in constructions where low weight, flexible dimensions and optimum conditions between dimensions are preferable.
