本标准的目的是描述、记录和定义交流至直流室外设备电源的试验方法。这些测试涉及交流输入参数和直流输出参数的测量。对电源采用统一的测试方法，可以在不同的电源之间进行公平的性能比较。本测试文件中有重复测试，其中许多测试可以同时进行。

The purpose of this standard is to characterize, document and define test methods for AC to DC outdoor plant power supplies. These tests involve the measurement of AC input parameters and DC output parameters. The application of uniform test methods for power supplies will allow fair performance comparisons to be made between different power supplies.There are repetitive tests throughout this test document, in which many of the tests can be combined and performed at the same time.
