BS EN 61558-1:2005 + A1:2009 Safety of power transformers, power supplies, reactors and similar products. General requirements and tests

BS EN 61558-1 deals with safety aspects of power transformers, power supplies, reactors and similar products such as electrical, thermal and mechanical safety. This standard covers the various types of dry-type transformers, power supplies, including switch mode power supplies, and reactors, the windings of which may be encapsulated or non-encapsulated .

BS EN 61558-1 also applies to transformers, power supplies, switch mode power supplies, and reactors incorporating electronic circuits. This standard does not apply to external circuits and their components intended to be connected to the input and output terminals or socket-outlets of the transformers, power supplies and switch mode power supplies, and reactors.
