The dimensions displayed in the simulator correspond to simple transformers, with a primary winding and a secondary winding (low voltage 0–50 V).
For transformers with multiple windings (including some high-voltage windings) and equipped with electrostatic and magnetic shields, the dimensions will be larger.
For more complex transformers, we recommend that you contact us in advance so that we can provide you with the exact dimensions if needed.
Be careful to take into account the voltage difference depending on the load when choosing a transformer or measuring its secondary voltage. The rated voltage specified by the manufacturer differs from the no-load voltage that can be measured directly on the transformer.
Manufacturers specify a rated voltage based on a 100% load; however, under no-load conditions, transformers may exhibit an overvoltage of 5% to 30%, depending on the internal resistance of the relevant winding.
Mains voltage also affects the output voltage—for instance, if you order a transformer with a 230V primary rating but the actual mains voltage is 239V.

We offer a service of custom toroidal transformers built according to your needs. There is no minimum order quantity (you can ask for one piece only).
Custom transformers are available in three profiles (standard / low / high) with several types of optional supports.
Our toroidal transformers have a class IP00 protection, class B insulation. They are subjected to a 4kV flash test and comply with ISO9001 TUV CERT.


Use the tool below to specify the characteristics of your custom toroidal transformer. Price is calculated automatically.
If your toroidal transformer has to meet special requirements or characteristics that lay beyond the capabilities of this calculator, please contact us to request a personalized quote.
