Notes on choosing a Switching Power Supply?
• To increase the lifetime of the S.P.S., we suggest users choosing the model that has the rating of 30% more power than actual need. For example, if the system needs a 100W source, we suggest that users may choose a S.P.S. with 130W of output power or more. By doing this, you can effectively boost the lifetime of the S.P.S. in your system. • We also need to consider about ambient temperature of the S.P.S. and whether there is additional equipment 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 Mean Well’s web site. • Choosing all kinds of function based on your application: • Protection function: Over Voltage Protection (OVP), Over Temperature Protection (OVP), Over Load Protection (OLP), etc. • Application function: Signaling Function (Power Good, Power Fail), Remote Control, Remote Sensing, etc. • Special function:
