描述了一种规定提供直流的低压电源设备（包括开关型）要求的方法。输出高达200 V直流。功率水平高达30 kW，通过交流运行。或者华盛顿。电源电压高达600 V。这些器械在I类设备中使用，或在有足够的电气和机械保护的情况下用于独立操作，但医疗应用和玩具除外，在这些应用中需要特殊考虑。 本合并版本由第一版（1993年）组成 及其修正案1（2001）。因此，无须在 本出版物的补充。

Describes a method of specifying requirements for low-voltage power supply devices (including switching types) providing d.c. output(s) up to 200 V d.c. at a power level up to 30 kW, operating from a.c. or d.c. source voltages of up to 600 V. The devices are for use within class I equipment or for free-standing operation when used with adequate electrical and mechanical protection, except for medical applications and toys, where special considerations apply. This consolidated version consists of the first edition (1993) and its amendment 1 (2001). Therefore, no need to order amendment in addition to this publication.
