Advantages and functions of DC module power supply(3)

The power module has a variety of input and output options, and can add repeatedly or cross add to form a modular combined power supply to achieve multiple input and output. Compared with the split type, the debugging is simpler and safer, which greatly simplifies the design and application and shortens the development time.

3. High reliability

A modular power supply is a power supply that can be directly mounted on a printed circuit board and can be used for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field programmable gate arrays (FPGAs) and other Digital or analog loads provide power. Typically, such modules are referred to as load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the obvious advantages of the modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communications fields, as well as automotive electronics, aerospace, etc.

The module generally adopts automatic process to ensure quality and reliability. The DC module power supply has been selected by the professional power research and development team according to strict standards, and has been designed and developed, and has undergone sound reliability testing and batch production testing. However, the split type scheme is difficult to conduct in-depth testing.

4. High power, density and efficiency

The module generally adopts multilayer PCB aluminum back substrate, which has high power density and small volume, saving the system space. At present, the 1/4 brick of DC-DC module is up to 1000W, and the split type scheme is difficult to meet this standard.
