A power supply complying with the requirements of this standard that is to be used for any of these purposes shall be capable of being mounted inside an en
39、closure that will provide the required attack resistance, or shall be provided with an enclosure that will provide the required attack resistance. See UL 365, UL 609, UL 1076, UL 1610, and UL 1635 to determine the attack resistance requirements that will apply. 2 General 2.1 Components 2.1.1 Except
40、as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered by this standard. 2.1.2 A component is not required to comply with a speci
41、c requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating established for the intended cond
42、itions of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic condition

44、explanatory or approximate information. 2.2.2 Unless otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted
45、 as referring to the latest edition of that code or standard. 2.4 Terminology 2.4.1 The term product as used in these requirements refers to all power supplies or any part thereof covered by these requirements unless specically noted otherwise. 3 Glossary 3.1 For the purpose of these requirements, t
46、he following denitions apply. 3.2 CIRCUITS, ELECTRICAL: a) HIGH-VOLTAGE (CLASS 1) A circuit involving a potential of not more than 300 volts and having circuit characteristics in excess of those of a low-voltage, power-limited circuit. b) LOW-VOLTAGE A circuit involving a potential of not more than
47、30 volts AC rms (42.4 volts DC or AC peak). c) POWER-LIMITED A circuit whose output is limited as specied in Power-Limited Circuits, Section 25. d) CLASS2Acircuit in which the voltage and power limitations are in accordance with the requirements of Table 25.1 for AC circuits and Table 25.2 for DC ci
