Toroidal transformers

Compared to conventional E-I transformers, toroidal transformers have nearly ideal magnetic circuits, which result in lower stray magnetic fields, less volume and weight, less audible hum and higher efficiency. Topmark toroidal transformers offer custom primary and secondary voltage, custom mounting and enclosures to meet customer requirements, low height and easy configuration into minimal space, low temperature rise, low core loss, and high efficiency.
Available in a wide power range – from 50VA to 5000VA.
