SIST EN 50563:2012/A1:2014

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.

Overview

SIST EN 50563:2012/A1:2014 is a European standard developed by CLC (European Committee for Electrotechnical Standardization) that defines the methodology for determining the no-load power consumption and average efficiency of active modes in external power supplies. This standard applies to both external alternating current to direct current (a.c.-d.c.) and alternating current to alternating current (a.c.-a.c.) power supplies. It supports the implementation of energy efficiency and ecodesign requirements under EU regulations aimed at reducing power wastage and promoting sustainable energy consumption in electronic devices.

Key Topics

• No-Load Power Measurement
  The standard provides a detailed procedure for measuring the no-load power, which is the power consumed by an external power supply when it is connected to the mains but not supplying any load. Minimizing no-load power is critical to reducing unnecessary energy consumption and aligning with energy efficiency directives.

• Average Efficiency in Active Modes
  SIST EN 50563:2012/A1:2014 specifies how to calculate the average efficiency of power supplies when operating under typical active load conditions. This metric is essential to evaluate the energy performance during normal device operation.

• Testing and Reporting
  It establishes testing methodologies and the parameters for producing test reports, ensuring that measurement results are consistent, reliable, and transparent for manufacturers and regulatory bodies.

• Compliance with EU Ecodesign Directive
  This standard supports compliance with Commission Regulation (EC) No 278/2009, which enforces ecodesign requirements for external power supplies to reduce environmental impact and improve energy efficiency. Adoption of EN 50563 offers a presumption of conformity with these regulations.

Applications

SIST EN 50563:2012/A1:2014 is widely used by:

• Manufacturers of External Power Supplies:
  Design and test external power supplies to meet ecodesign regulations and optimize for low no-load power consumption and high active mode efficiency.

• Regulatory Agencies and Market Surveillance:
  Verify the compliance of power supply products with EU energy efficiency standards and directives.

• Product Certification Bodies:
  Facilitate the certification and labeling of external power supplies in accordance with European energy efficiency benchmarks.

• Energy Efficiency Consultancy:
  Assess power supply performance as part of broader energy audits and sustainability initiatives for electronic equipment.

Related Standards

• Commission Regulation (EC) No 278/2009 (implementing Directive 2005/32/EC, now replaced by 2009/125/EC)
  Regulates ecodesign requirements specifically targeting the no-load power consumption and average active efficiency of external power supplies.

• EN 50563:2011
  The original standard which the amendment A1:2013 modifies, ensuring updated and improved procedures.

• IEC 62301
  Related standard covering measurement of standby power, complementing no-load power evaluation in power supplies.

• EU Directive 2009/125/EC
  Establishes a framework for ecodesign requirements across energy-using products sold in the European market.
