A transformer should fit the system, not force the system to fit the catalogue.
ESTABLE matches equipment requirements to the right transformer or power-conversion product. Each project starts with the application and moves through an approved drawing, sample, test plan and controlled production release.
Eight product groups.
One point of technical responsibility.
From 20 W compact transformers to large equipment assemblies, each product is selected as part of the complete power system.
Toroidal Transformers
Custom toroidal transformers from 20 W to 20 kW, adapted to the equipment envelope.

Start from what you know.
Choose a published range.
Power, voltage and dimensions are already defined. Confirm fit and availability.
Search standard ranges 02 / MODIFYAdapt the standard.
Change a winding, terminal, mounting height, insulation class or enclosure.
Configure the requirement 03 / REPLACEReconstruct the requirement.
Begin with a drawing, nameplate, failed unit or incomplete legacy specification.
Start from a nameplateCAPTURE
Every critical assumption has a place in the file.
The specification, drawing, sample and production record remain connected. That makes changes visible and repeat orders easier to control.
- 01Review
We organize the drawing, nameplate, application and missing data.
- 02Specify
The electrical and mechanical route is confirmed by an engineer.
- 03Sample
A paid sample is checked for form, fit and function.
- 04Produce
Approved configuration, test records and batch documentation.
Look beyond the render.
Winding, encapsulation and dielectric testing are visible parts of the production route. Manufacturing is carried out by qualified partner facilities.
Do not hide the difficult questions. Resolve them before the build.
Answers before
the first purchase order.
The information an engineer needs to move from an application note to an approved transformer design.
A practical comparison of size, magnetic field, mechanical noise, thermal behavior and cost drivers.
How to define the isolation boundary, load, leakage, voltage and documentation before selecting a design.
A practical checklist for replacing a failed transformer when drawings or the original supplier are unavailable.
