Toroidal transformers: they produce up to 3000VA power 10VA
Toroidal transformers ensure a lower flow of dispersion and low losses by eddy currents. These transformers can be built both with encapsulated as without it, and they produce 10VA transformer up to 3000VA power.
Similarly, they have different configurations, or for one or more outputs, for wiring or encapsulated electrostatic and electromagnetic.
