Summary
This standard specifies the output DC voltage below 250V, power is less than 30kW, the 600V ac or dc source voltage low-voltage power supply devices (including switching type) determine the technical requirements of the method. The power supply device for use in Class I, or when there is sufficient electrical, mechanical protection conditions run independently. This standard applies to any of outputs, powered by AC or DC power supply for all types of applications as well as other unknown customized products.
