3000/RX-8D4A-A-13-MM-ST power module

Generally, such modules are called load (POL) power supply systems or point-of-use power supply systems (PUPS). Because of the advantages of modular structure, it is widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, router and other communication fields, automotive electronics, aerospace and so on.
Especially in recent years, due to the rapid development of data service and the continuous promotion of distributed power supply system, the increase of module power supply has exceeded the primary power supply. Module power supply has the function of isolation, strong anti-interference ability, own protection function, easy to integrate. With the extensive use of semiconductor technology, packaging technology and high-frequency soft switch, the power density of modular power supply is increasing, the conversion efficiency is increasing, and the application is becoming simpler.

People in the field of switching power supply technology is to develop related power electronic devices, while developing switching frequency conversion technology, the two promote each other to promote the switching power supply to light, small, thin, low noise, high reliability, anti-interference direction with more than two digit growth rate every year. Switching power supply can be divided into AC/DC and DC/DC two categories, DC/DC converter has realized modularization, and the design technology and production process at home and abroad have been mature and standardized, and has been recognized by users, but the modularization of AC/DC, because of its own characteristics in the process of modularization, encounter more complex technology and process manufacturing problems. The structure and characteristics of the two types of switching power supply are described below
