Industrial electrical transformers are subject to a set of standards and regulations to ensure their safety, performance and compliance with European and environmental requirements. At Le Cosinus, we ensure that our processors strictly comply with these regulations to offer our customers reliable and sustainable solutions.

Our transformers are designed and tested in accordance with the International Electrotechnical Commission (IEC), which is the international standardization organization for the fields that concern us: Electricity, Electronics and Electromagnetic Compatibility. The NF or EN standards are themselves integrated into IEC standards. There is no longer any need to differentiate between them.
