IEC EN 60647 Test for Dimensions of Magnetic Oxide Cores Intended for Use in Power Sources

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60647 testing. This standard specifies the physical and magnetic dimensions of EC cores made from magnetic oxides for use in high flux density applications.

It covers cores specifically designed for use in power transformers, such as switched-mode power supplies, typically operating at a switching frequency of 25 kHz. Lists preferred dimensions of cores, with tolerances, as long as mechanical and electrical interchangeability are important.

Parties interested in making or using EC-cores may find it tempting to set local standards for everyday use. In doing so, care must be taken not to exclude any other type of EC core that meets the IEC primary standard and also meets the user's requirements.

The national standard complies with the dimensional requirements of this IEC standard, but more details are provided to encourage practical use of the standard.

Other solutions are possible under this IEC standard and should not be excluded if such cores and formers are functionally interchangeable with those conforming to the national standard.
