What is the working principle of switching power supply?As the world pays more attention to energy issues, the energy consumption of electronic products will become more and more prominent. How to reduce their standby power consumption and improve power supply efficiency has become an urgent problem

For switching power supply is not unfamiliar to everyone, it is very widely used, and has the advantages of stable and reliable voltage, low power consumption, high conversion efficiency, so it is mostly used in television equipment. For example, optical amplifiers, digital satellite receivers, modu

Switching power supply is mostly used in automation equipment as the power supply of PLC, field digital quantity, and instrument. Its appearance structure is divided into two types: one is the ordinary switching power supply, which is fixed with screws during installation.

According to the use situation, determine the voltage, current, current size, installation method, and power required by the switching power supply, and then select the switching power supply suitable for each function.
