Safety of transformers, reactors, power supply units and combinations thereof - Part 2-26: Particular requirements and tests for transformers and power supply units for saving energy and other purposes
 N EN 61558-2-26

Annotation

Replacement:

This part of IEC 61558 deals with the safety of transformers, power supply units and switch mode power supply units all for saving energy and other purposes in electrical installations by adjusting the output voltage and/or other electrical characteristics on the output circuits without interruption affected by the transformers, power supply unit and switch mode power supply unit.

NOTE 1 Safety includes electrical, thermal and mechanicals aspects.

The saving of energy is obtained by voltage stabilization and/or voltage adjusting of the electrical installation. This standard may also be used for power supply units and switch mode power supply units intended to be used where adjusting of the voltage or other electrical characteristics is required by the final application.

NOTE 2 An example of electrical installation is lighting installations, outdoor or indoor.

NOTE 3 In special applications the reduction of the output voltage may affect the safety and the performance of the supplied equipment.
