Ecodesign requirements for small power transformers

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.

Anforderungen an die umweltgerechte Gestaltung von Kleinleistungstransformatoren

Diese europäische Norm enthält Anforderungen an die umweltgerechte Gestaltung von Kleinleistungstrans¬formatoren, die der Reihe EN 61558 entsprechen und auf die in der Verordnung (EU) Nr. 548/2014 der Kommission zur Umsetzung der Richtlinie 2009/125/EG Bezug genommen wird. Diese europäische Norm ist auf Transformatoren mit 50-Hz-Wechselspannungseingang und -ausgang mit einer Bemessungsleistung von 1 kVA oder mehr und einer Spannung unterhalb von 1 kV mit Ausnahme der in der Verordnung ausgenommenen Transformatoren anwendbar. Für Transformatoren mit einer Spannung zwischen 1 kV und 1,1 kV kann diese Norm als Leitfaden benutzt werden.

Exigences en matière d’écoconception applicables aux transformateurs de faible puissance

La présente Norme européenne donne les exigences en matière d'écoconception applicables aux transformateurs de faible puissance conformes à la série EN 61558 et en relation avec le Règlement de la Commission (UE) No. 548/2014 mettant en œuvre la Directive européenne 2009/125/CE. La présente Norme européenne s'applique aux transformateurs ayant des entrées et sorties en courant alternatif de 50 Hz avec une puissance assignée de 1 kVA ou plus et une tension inférieure à 1 kV, à l'exception de ceux qui sont exclus dans la réglementation. Pour les transformateurs avec une tension comprise entre 1 kV et 1,1 kV, la présente norme peut être utilisée comme guide.

Zahteve za okoljsko primerno zasnovo majhnih močnostnih transformatorjev

Ta evropski standard določa zahteve za okoljsko primerno zasnovo majhnih močnostnih transformatorjev, ki so v skladu s skupino standardov EN 61558 v povezavi z Uredbo Komisije (EU) št. 548/2014 o izvajanju Direktive 2009/125/ES.
Ta evropski standard se uporablja za transformatorje z vhodom in izhodom 50 Hz AC z nazivno močjo 1 kVA ali več in napetostjo manj kot 1 kV, razen za tiste, ki so izključeni iz uredbe.
Za transformatorje z napetostmi 1–1,1 kV se ta standard lahko uporabi kot vodilo.

This European Standard was approved by CENELEC on 2017-07-31. CENELEC members are bound to comply with the CEN/CENELEC

Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC

Management Centre or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation

under the responsibility of a CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the

same status as the official versions.

1 Scope

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.

2 Normative references
Not applicable.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

NOTE Unless otherwise specified, the terms “voltage” and “current” imply the r.m.s. values of alternating

voltage and current.
3.1
(power) transformer

static piece of apparatus with two or more windings which, by electromagnetic induction, transforms a

system of alternating voltage and current into another system of voltage and current usually of

different values and at the same frequency for the purpose of transmitting electrical power

[SOURCE: IEV 421-01-01]

Note 1 to entry: The term frequency also implies that the waveform remains the same.

3.2
short-circuit voltage

voltage to be applied to the input winding, when the windings are at ambient temperature, to produce

in the short-circuited output winding a current equal to the rated output current

Note 1 to entry: The short-circuit voltage is usually expressed as a percentage of the rated supply

voltage.
3.3
rated output current

output current at rated supply voltage, rated supply frequency and rated output voltage, at rated power

factor, assigned to the transformer by the manufacturer for the specified operating conditions of the

transformer
3.4
rated supply voltage

supply voltage (for polyphase supply, the phase-to-phase voltage) assigned to the transformer by the

manufacturer for the specified operating conditions
