- Scope
- This standard specifies the method for determining the technical requirements of low-voltage power supply equipment (including switching type) with output DC voltage below 250V, power below 30KW, and powered by AC or DC source voltage below 600V. When used for electrical or mechanical protection, the device is used within the scope of Class I equipment, or operates independently. This standard covers all types of equipment powered by AC or DC, with any number of outputs, including power supplies for military, industrial, telecommunications, and commercial applications. In special cases adapted to medical and toys. This standard does not apply to underwater and similar special occasions, nor does it apply to medical equipment with live parts that can penetrate into the human body. This standard allows to specify a technical parameter capable of meeting the technical performance level required by power supply equipment for special purposes, and to establish basic definitions related to this type of equipment, as well as to determine specific technical requirements. It enables manufacturers and users to select and determine the scope of application of their power supply equipment according to the specified technical requirements. However, the indicators given in each sub-clause of the current IEC publications must be complied with.
