What information do you need to design a custom transformer?

Please share input voltage and frequency, output voltage(s) and current, rated power, operating frequency for high frequency designs, isolation and safety requirements, size or mounting limits, ambient temperature, target standards and estimated annual quantity. A circuit diagram or reference sample speeds up the engineering review.

Do you support OEM and ODM projects?

Yes. We build to customer drawings (OEM) and also develop designs from your electrical specification (ODM), including private labeling, custom packaging and connector or cable changes.

Which tests are performed before shipment?

Depending on the product, inspection includes LCR measurement, DC winding resistance, impulse winding test, hi-pot dielectric strength test, power and efficiency measurement with an AC power source and digital power meter, aging test and final visual inspection.

Can you design to international safety standards?

Designs can be engineered to target requirements such as IEC 61558 for transformers or IEC 62368-1 for power adapters. Certification scope and available test reports are confirmed for each specific model during the engineering review.
