Single-phase toroidal transformer, power range from 20VA to 15kVA. Designed and tested according to EN61558. Suitable for installation in electronic equipment and 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 the primary side. Up to 50% less weight than a similar conventional transformer. Low magnetisation currents and no-load losses.
Suitable as a safety isolating transformer in applications where low weight, flexible dimensions, and optimum conditions between dimensions are preferable.
