Purchase points:
1, choose the appropriate input voltage range. AC input, for example, commonly used input voltage specifications 110V, 220V, so there is a 110V, 220V AC switching, as well as universal input voltage (AC: 85V-264V) three specifications. Input voltage specifications should be selected according to the area of use.
2, choose the right power. Switching power supplies consume a portion of the power during operation and release it in the form of heat. In order to increase the life of the power supply, it is recommended to choose a model with 30% more output power rating.
3. Consider load characteristics. In order to improve the reliability of the system, it is recommended that the switching power supply work at 50% -80% load is good, that is, assuming that the power used is 20W, the output power should be selected 25W-40W switching power supply.
