Choose the appropriate input voltage range: Take AC input as an example, the commonly used input voltage specifications are AC110V, AC220V, so there are corresponding 110V, 220V AC switch, and general input wide voltage (AC: 100V-277V) three specifications. Input voltage specifications should be selected according to the area of use.

Considering the load characteristics: In order to improve the reliability of the system, it is recommended that the constant voltage LED power supply work at 50%-80% of the load, that is, assuming the used power is 20W, the LED power supply with the output power of 25W-40W should be selected.

In addition, consider the ambient temperature of the power supply, the availability of additional auxiliary heat dissipation devices, and the place where the power supply is used. If the power supply needs to be reduced in an excessively high working environment, see the output reduction curve of the ambient temperature. If it is used in outdoor places, but also take into account the waterproof requirements of LED power supply.
