K-Factor single-phase transformers are manufactured with the highest quality materials and tested according to EN61558 standards.

All single-phase transformers, whether laminated or toroidal, consist of enameled electrolytic copper windings on insulating supports. Maximum care is taken with insulation, allowing products to be tested for dielectric strength at voltages significantly higher than the minimum regulatory requirements, ensuring reliability and durability over time.

Operating temperatures are also monitored and periodically checked in endurance and overtemperature tests to guarantee maximum performance under limit load or airflow conditions.

They are distinguished into separation transformers (EN61558-2-1), control transformers (EN61558-2-2), isolation transformers (EN61558-2-4), and safety transformers (EN61558-2-6) depending on usage needs and working conditions. Plastic or metal enclosures are available for many products to provide protection against accidental contact.

The best technical and electrical characteristics are found in K-Factor single-phase transformers.
