Tips on choosing a switching power supply
(1) 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.


(2) We also need to consider about ambient temperature of the S.P.S. and whether there is additional device for dissipating the heat. If the S.P.S. is working in a high temperature environment, we need to make some derating to
the output power. The derating curve of “ambient temperature” versus “output power” can be found on our spec sheets.
(3) Choosing functions based on your application:
●Protection function: Over Voltage Protection (OVP), Over Temperature   Protection (OVP), Over Load Protection (OLP), and etc.
●Application function: Signaling Function (Power Good, Power Fail), Remote  Control, Remote Sensing, and etc.
●Special function: Power Factor Correction (PFC), Uninterruptible Power   Supply (UPS) function.
(4) Make sure that the model qualifies for the safety standards and EMC regulations you need.
