For additional definitions, see IEEE 100. Power Source, Class 2An elect

31、rical source, such as a transformer, power supply, or battery, having an open-circuit voltage that is less than 30 V rms (42.4 V peak) or 60 VDC and having limited energy available in the circuit under load conditions, including short-circuit and extremely low resistance. A Class 2 supply source can

32、 be either inherently limited or non-inherently limited. a) Inherently Limited Power SourceA transformer, power supply, or battery having no discrete protective device that is relied upon to limit the output energy available from the supply. A power supply or battery with internal current and energy

33、 limiting circuitry shown to be reliable is eligible to be identified as inherently limited. Transformers, power supplies, and batteries may be provided with protective devices as long as they are not relied upon to limit the output. b) Non-Inherently Limited Power SourceA transformer, power supply,

34、 or battery having a discrete protective device that automatically interrupts the output when the current and energy output reaches a prescribed limit. NOTEThe above is in reference to U.S. products. Products intended for use outside the U.S. should comply with the applicable standards of those coun
