DIN EN 50563:2012-09

This European Standard specifies methods of measurement of electrical power consumption, and the documentation of results, for external power supplies. This standard is applicable to external power supplies with a rated input voltage within the range 100 V a.c. to 250 V a.c. having a single output with a rated output power not exceeding 250 W and a rated output voltage not exceeding 230 V a.c. or 235 V d.c. The output voltage may be either at a fixed voltage, or at a voltage which is user selectable, or at a voltage that is automatically selectable by the external power supply so as to be compatible with one or more product-loads. The responsible committee is K 711 "Sicherheit elektronischer Einrichtungen für Audio/Video-, Informations- und Kommunikationstechnik" ("Safety of electronic equipment within the field of audio/video, information technology and communication technology") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
