What is BS EN IEC 60938-2 about?
BS EN IEC 60938-2 is the second part of Fixed inductors for electromagnetic interference suppression in multi-series.
BS EN IEC 60938-2 applies to fixed inductors designed for electromagnetic interference suppression, which will be connected to an AC mains or other supply with a nominal voltage not exceeding 1 000 V AC RMS or 1 500 V DC with a nominal frequency not exceeding 400 Hz.
Who is BS EN IEC 60938-2 for?
BS EN IEC 60938-2 on Fixed inductors for electromagnetic interference suppression is useful for:
- Manufacturers of electronic devices
- Manufacturer of automobile
- Electricians
Why should you use BS EN IEC 60938-2?
Inductors are used as energy storage devices in switch-mode power devices to produce DC current. The inductor is a passive electronic component that can store electric energy in form of magnetic energy.
BS EN IEC 60938-2 helps with the following processes:
- In performing the safety test for approval of inductors
- Reducing the defects by examining the fixed inductor visually.
- With guidelines for the method to resist the line and insulation this line resistance between any input terminal and the corresponding output terminal helps in measuring the DC current.
- Not exceeding the working temperature of the internal insulation of the inductor.
- In resisting the soldering heat and sustaining the inductors in different climatic conditions.
- Speed up the process of conducting appropriate test methods and utilize standard requirements in performing safety tests.
- In measuring the performance of suppression inductors.
- Classifying the electromagnetic interference suppression inductor into different climatic categories.
What’s changed since the last update?
BS EN IEC 60938-2:2021 supersedes BS EN IEC 60938-2:2000. BS EN IEC 60938-2:2021 includes some technical changes with respect to BS EN IEC 60938-2:2000. These include:
- The test plan for performance testing has been removed, mandatory safety tests and optional
- Performance tests are listed in one test plan in Annex B
- Requirements for Thyristor-Chokes have been withdrawn
- Material requirements are harmonized with IEC 60939-3 and UL 60939-3; AC chokes up to 1 000 V and DC chokes up to 1 500 V are now in the Scope
