- Scope
- This standard specifies the method for determining the technical requirements for low-voltage power supply equipment (including switch-type) with output DC voltage below 250 V, power below 30 kW, and powered by AC or DC source voltage below 600 V. The power supply is used in industrial equipment, or operates independently with sufficient electrical and mechanical protection. This standard applies to all types of power supplies with any number of outputs, powered by AC or DC, and to products custom-made for other unknown applications. For those power supplies developed as part of equipment for which special product standards exist, these special product standards are also applicable to such power supplies; especially when product standards are not sufficient to cover some performance characteristics of these power supplies, the supplementary use of this standard can be used as a A useful option. This standard allows the specification of technical parameters to meet the required performance levels of power supply equipment for a specific purpose, establishes basic definitions related to this type of equipment, and establishes specific technical requirements. These enable manufacturers and users to select and determine the scope of application of their power supply equipment according to the specified technical requirements.
