What should I pay attention to when selecting the module of the acdc module?(3)


Module power

The isolation feature makes the input and output of the module completely become two independent (not sharing the ground) power supplies. In the industrial bus system, it is necessary to conduct safety isolation in the face of harsh environment, such as peak value, lightning stroke and arc interference, which can also eliminate the grounding environment; In hybrid circuit, noise isolation of sensitive analog circuit and digital circuit; Voltage conversion is realized in multi voltage power supply system.

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.

4. Output power.

After the load is selected, the output current is basically determined. The size of the load current is the key to determine the power, and also directly affects the reliability and price of the module. Under the premise of using at room temperature, themodule should be used at 30% - 80% power. If it is a high temperature or low temperature environment, specific decrement design should be considered. One of the key factors for successful design is to select the appropriate output current. If the current is too large or too small, it will lead to low reliability and high cost.
