External a.c. - d.c. and a.c. - a.c. power supplies - Determination of no-load power and average efficiency of active modes
This European Standard specifies methods of measurement of electrical power consumption, and the reporting of results, for external power supplies. This standard is applicable to external power supplies with a rated input voltage within the range 100 V ac to 250 V ac 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 325 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.

Samostojne (zunanje) usmerniške (AC-DC) in transformatorske (AC-AC) naprave - Ugotavljanje moči brez obremenitve in povprečnega izkoristka aktivnih načinov
Ta evropski standard določa metode merjenja porabe električne energije in poročanje rezultatov za samostojne (zunanje) usmerniške (AC-DC) in transformatorske (AC-AC) naprave. Ta standard velja za zunanje usmerniške in transformatorske naprave z ocenjeno vhodno napetostjo v razponu od 100 V izmeničnega toka do 250 V izmeničnega toka, ki imajo enojni izhod z ocenjeno izhodno močjo, manjšo od 250 W, in ocenjeno izhodno napetostjo, ki je manjša od 230 V izmeničnega toka ali 325 V enosmernega toka. Izhodna napetost je lahko stalna napetost ali napetost, ki jo izbere uporabnik, ali napetost, ki jo avtomatsko izbere samostojna (zunanja) usmerniška (AC-DC) in transformatorska (AC-AC) naprava, ki je skladna z eno ali več produktnimi obremenitvami.

Introduction
This European Standard was written in response to an EC mandate requesting the creation of a
harmonised standard providing a reliable, accurate and reproducible method of measuring the no-
load power consumption and determining the average efficiency of active modes for external power
supplies, which takes into account the generally recognised state of the art measurement methods.
This standard makes extensive reference to EN 50564 Electrical and electronic household and
office equipment - Measurement of low power consumption, which was also prepared under an EC
mandate to support the ecodesign Directive. Other provisions are based on the test method
published by the EPA and the Australian/NZ Standard AS/NZS 4665.1.
The methods defined in this standard are intended to cover no-load power consumption and
average efficiency of active modes for a.c. - a.c. and a.c. – d.c. external power supplies.
The aim is to ensure this European Standard is compatible with the objectives of EU legislation for
ecodesign. This standard is applicable to a wider range of products than EC Regulation
No 278/2009.

1 Scope
This European Standard specifies methods of measurement of electrical power consumption, and
the reporting 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 325 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.
NOTE 1 This document has been written in particular to support EC Regulation No 278/2009 for the measurement of no-
load condition electric power and average efficiency of active modes for external power supplies.
NOTE 2 This standard does not specify safety requirements for products nor safety precautions to be taken by those
performing measurements. It does not specify minimum performance requirements, nor does it set maximum limits on
power or energy consumption.
