External a.c. - d.c. and a.c. - a.c. power supplies - Determination of no-load power and average efficiency of active modes; German version EN 50563:2011
Externe AC/DC- und AC/AC-Netzteile - Bestimmung von Nulllast und durchschnittlicher Effizienz im Betrieb; Deutsche Fassung EN 50563:2011
Overview
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.
