What does a DC conversion power supply look like?(5)

Distributed Power Supply System
The distributed power supply system uses low-power modules and large-scale control integrated circuits as basic components, and uses the latest theoretical and technological achievements to form a building block-type, intelligent high-power power supply, so that the strong and weak currents are closely combined and the high power is reduced. Components, high-power devices (centralized) development pressure, improve production efficiency.

Regardless of how much control the product material and production process are, aging needs to be checked. Because the incoming inspection of electronic components and transformers is difficult to control, the quality stability of this batch of power supplies and whether the materials are detected to have potential safety hazards can only be detected through aging and high-temperature sampling of the entire batch of power supplies.
