How to Maintain Power AdapterWhen maintaining the power supply equipment, we need to have a deep understanding of the power supply equipment. Usually, the power adapter equipment will be marked with the nominal voltage. What does the nominal voltage mean? Generally, the nominal voltage refers to the output voltage, that is, the voltage without any load and no current output. Generally speaking, the common power adapter is the real no-load voltage, which is different from the standard voltage used by people everyday. Therefore, the consistency of electronic components is very high. However, in real life, if the power adapter wire is broken and replaced with a non-conforming wire, the switching power adapter is changed. It has caused some influence.
