IEC 61204-7:20 16 EXV包括IEC 62477-1:20 12中涉及的一般规则的规定。扩展版不是IEC官方标准。只有相关标准的当前版本才被视为正式文件。扩展版只有英文版本。 IEC 61204-7:20 16规定了由电源电压高达1 000 V AC或1 500 V DC供电的开关模式电源（SMPS）单元的安全要求，提供交流和/或DC输出，建立交流主电源的逆变器输出除外。本产品标准涵盖本文档中定义的独立SMP和组件SMP。DC电力和配电设备，向通常用于信息和通信技术设备安装的其他设备提供、分配、监控和控制隔离的二次电路电力。与上一版相比，此版本包括以下重大技术变更: a)使用IEC 62477-1作为参考文件，而不是IEC 60950-1； b)对标题的修改，删除“直流输出-”字样，并添加“开关模式”。

IEC 61204-7:2016 EXV includes the provisions of the general rules dealt with in IEC 62477-1:2012. The Extended version is not an official IEC Standard. Only the current versions of the related standards are to be considered the official documents. The Extended version is available in English only.

IEC 61204-7:2016 specifies the safety requirements for switch mode power supply (SMPS) units supplied by source voltages up to 1 000 V AC or 1 500 V DC providing AC and/or DC output(s), except inverter output(s) establishing AC mains. This product standard covers both stand-alone and component SMPS as defined in this document. DC power and distribution equipment which provides, distributes, monitors, and controls isolated secondary circuit power to other equipment typically used in information and communication technology equipment installations. This edition includes the following significant technical changes with respect to the previous edition:
a) use of IEC 62477-1 as reference document, instead of IEC 60950-1;
b) modification of the title by deleting the wording "DC output-" and adding "switch mode".
