BS EN 50645:2017

This standard BS EN 50645:2017 Ecodesign requirements for small power transformers is classified in these ICS categories:

• 29.180 Transformers. Reactors

This European Standard gives Ecodesign requirements for small power transformers complying with the EN 61558 series and in relation to Commission Regulation (EU) N° 548/2014 implementing the European Directive 2009/125/EC.

This European Standard is applicable to transformers with 50 Hz AC input and output with a rated power of 1 kVA or more and a voltage lower than 1 kV, except those excluded in the regulation.

For transformers with a voltage between 1 kV and 1,1 kV, this standard may be used as a guide.
