Low-voltage power supply devices, d.c. output - Performance characteristics

Describes a method of specifying requirements for low-voltage power supply devices (including switching types) providing d.c. output(s) up to 200 V d.c. at a power level up to 30 kW, operating from a.c. or d.c. source voltages of up to 600 V. The devices are for use within class I equipment or for free-standing operation when used with adequate electrical and mechanical protection, except for medical applications and toys, where special considerations apply.

Stromversorgungsgeräte für Niederspannung mit Gleichstromausgang - Eigenschaften

Dispositifs d'alimentation à basse tension à sortie en courant continu - Caractéristiques de fonctionnement

Décrit une méthode de prescription des caractéristiques pour les alimentations basse tension (y compris les alimentations à découpage) jusqu'à 200 V c.c. à la sortie et de puissance inférieure à 30 kW, opérant à partir d'une tension de source continue ou alternative limitée jusqu'à 600 V. Les unités sont prévues pour utilisation à l'intérieur d'équipement de classe 1 ou en opération autonome avec des protections électriques et mécaniques adéquates, à l'exception des applications médicales et des jouets où des considérations spéciales sont applicables.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in
...
