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.
How to build your custom transformer :
Version 1.20 : Please update your cache (ctrl+F5) to access new options.
You can now save your custom transformer template in a local file and load it for later use or edit
- Use the "SAVE TEMPLATE" button to save the file. - Use the "CHOOSE FILE" button to load your file.
Write the primary voltage of your transformer in the "PRIMARY CIRCUIT" section.
Then, input the voltage and max intensity of your first secondary winding in the "SECONDARY CIRCUIT" section.
To add a new winding (primary or secondary) click the "NEW WINDING" button in the adequate section. A new line appears. Do not forget to specify the voltage and intensity that you need. "
You can remove a winding with the button "REMOVE WINDING". Please note that your transformer must have at least one primary winding and one secondary winding.
You can add intermediate cables to a secondary winding. It can be a midpoint (12-0-12V) or a free intermediate cable (0-3-5V). To do this, use the "EDIT" button on the corresponding secondary winding.
Caution : a winding cannot have a midpoint and free intermediate cables at the same time. You have to disable one to use the other.
Your custom transformer cannot have a unlimited number of cables. Leave the mouse cursor on any button that adds winding, midpoint or cable to know if you are close to those limitations.
Once satisfied with your coils, focus on the OPTIONS section. This section allows you to ask for an electrostatic screen, a magnetic screen and a thermal fuse. YOu can also specify the profile of your transformer and request a specific support. The choice of a support is optional and you can leave the default selection if your project does not require special mounting.
The "SUMMARY" section provide a summary of the windings values and all the options. Carefully check that the information is correct and complete : it is on this basis alone that your toroidal transformer will be built. If something is not writen here, it will not be a part of the transformer.
The Specifications section is given as an indication relative to the power and profile of your transformer. Please note that the proposed values do not include the support and the number of windings which can significantly affect the dimensions & weight.. The more winding and cables, the less precise are those numbers.
If something is wrong with the template, the app lists what is wrong under the options section. Until the errors have been solved, it is neither possible to save the template nor to add the transformer to cart.
After verifying the summary, choose a quantity and press the add to cart button. Remember, once in the list, the transformer can not be changed. The only way to modify it is to go to your cart, remove the transformer and start again.
