Scope: This document specifies the requirements for laboratory power supply characteristic measurement and establishes the procedure for laboratory power supply characteristic measurement. This document applies to: ——Testing within the maximum rated current range of the power supply; ——The tested sample is in normal working condition. This document does not apply to: --- Building power supplies for laboratories, such as power supplies for testing instruments, environmental chambers, lighting, etc. --- DC power supply for the DC electrical equipment under test. - Testing of photovoltaic arrays. The photovoltaic array generates its own electricity (if the auxiliary equipment used is connected to the branch circuit to which this document applies, this document applies to the testing of such photovoltaic array auxiliary equipment). --- Short-circuit current test, abnormal test, switching test and similar tests related to power supply capacity. --- Electromagnetic compatibility test.
