How to select switching power supply

With the development and innovation of power electronics technology, switching power supply technology is also being innovated. There are a wide variety of switching power supply products on the market. How to choose a practical switching power supply will be a required course.

1

First of all, according to their own needs, choose the appropriate input voltage specifications and appropriate power supply, but in order to make the switching power supply life growth, it is recommended to choose more than 30% output power rated models.

For example, if you need a 100W power supply, it is recommended to choose a model with the output power rating greater than 130W, and so on to effectively improve the service life of the switching power supply.

On this basis, it is also necessary to consider the load characteristics of the power supply and the operating environment temperature of the switching power supply, as well as whether there are additional auxiliary heat dissipation devices. When the ambient temperature is too high, the switching power supply needs to reduce the output.

3

Select various functions of switching power supply as required, such as:

Protection function: over voltage protection, over temperature protection, over load protection, etc

Application functions: signal function, remote control function, telemetry function, parallel function, etc

Special features: power factor correction, uninterruptible power supply

These functions are the switching power supply must have, because only in this way can make the switching power supply life increase.

Finally, according to the requirements of the selection of safety requirements and electromagnetic compatibility (EMC) certification.

Each type of switching power supply will be attached with a nameplate, the relevant parameters of the power supply displayed, so that people have a preliminary understanding of the power supply.

Just like the product nameplate of Reeba Electronics, you will know the product model, total power, output voltage and output current, certification and other information, so as to match the power product you need.

Each power supply comes with a separate specification that provides detailed information about the power supply.

Complete supporting facilities of the manufacturer can ensure the quality of the product, so that you have a "sense of security", with peace of mind.

Professional testing equipment (such as: Chroma electronic load, ATS, EMC testing laboratory), has obtained utility model patent certificate and ETL certification certificate.
