Answer:
1. To increase the reliability of switching power supply, 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 switching power supply with 130W of output power or more. By doing this, you can effectively boost the reliability of the switching power supply in your system.
2. We also need to consider about ambient temperature of the switching power supply and whether there is additional device for dissipating the heat. If the switching power supply is working in a high temperature environment, we need to make some derating to the output power. Requirement working temperature: -10 to 50 degree Celsius.
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.
