Toroidal transformers
Toroidal transformers standard range
Type RT
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.
Applications: Wiring diagram
Suitable as safety isolating transformer in constructions
where low weight, flexible dimensions and optimum
conditions between dimensions are preferable.
