Toroidal Transformers

A toroidal transformer is a special type of transformer. Insulated wires are wound around a closed ferrite core. With toroidal transformers, a primary voltage is transformed into a secondary voltage. Only AC voltage can be transformed.
The power is indicated in unit VA (VoltAmpere). Toroidal transformers are more expensive than conventional transformers, but higher efficiencies and lower scatter losses can be achieved.
Especially in audio applications, e.g. in amplifiers, these transformers are specifically used.
Our transformers usually have symmetrical output voltages: 2x6V, 2x9V, 2x12V, 2x15V, 2x18V, 2x24V and 2x115V.
In addition to the transformers, we also offer accessories such as inrush current limiters and mounting sets in different diameters.
