Notes on choosing a switching power supply?

To increase the reliability of the S.P.S., we suggest users choose a unit that has a rating of 30% more power than actual need. For example, if the system needs a 100W source, we suggest that users choose a S.P.S. with 130W of output power or more. By doing this, you can effectively boost the reliability of the S.P.S. in your system.Make sure that the model qualifies for the safety standards and EMC regulations you need.

What are switching power supplies?

Switching power supplies input a commercial AC power supply (such as 110 VAC or 220 VAC), uses a high-speed semiconductor switching process to convert the input to high-frequency electric power, and yields a direct current (such as 24 VDC).
