Toroidal Transformers

The wide range of Toroidal transformers from 8 to 20KVA, and their configuration of primary/secondary, single, dual, or multiple windings allow to get any required configuration.

Toroidal transformers has a lot of advantages in front of open frames, conventional transformers, radiation, volume/power relation, leakage inductance, low no-load losses, high efficiency, low operating temperature. Their use is highly recommended.
