Toroidal Transformers

Efiter offers a range of toroidal transformers providing a compact, silent, and highly efficient solution for power conversion and adaptation. Available in standard or custom-made versions, our transformers cover a wide power range and meet the most stringent requirements for reliability and safety.

What is a Toroidal Transformer?

A toroidal transformer is a transformer whose magnetic core is circular (ring-shaped), made of grain-oriented silicon steel. This design optimizes the power-to-volume ratio, limits losses, and reduces electromagnetic radiation. Lighter, quieter, and more efficient than conventional transformers, toroidal transformers are particularly suited for environments requiring compactness and low operating noise.

Specializing in custom transformers, Efiter offers a toroidal range designed for field reliability and diverse applications.
