1. In order to prolong the life of the POWER SUPPLY, it is recommended to select a model with an output power rating of 30% more. For example, if the system needs a 100W power supply, it is recommended to choose a model with an output power rating greater than 130W, and so on can effectively improve the life of the POWER SUPPLY.
2. In addition, it is necessary to consider the working environment temperature of POWER SUPPLY and whether there is any additional auxiliary heat dissipation equipment. When the ambient temperature is too high, POWER SUPPLY needs to derate the output. For the derating curve of ambient temperature to output power, please refer to the product specification.
3. Select various functions according to the application requirements:
• Protection functions: Over Voltage Protection (OVP), Over Temperature Protection (OTP), Over Load Protection (OLP), etc.
• Application function: signal function (POWER GOOD, POWER FAIL), remote control function, telemetry function, parallel function, etc.
• Special functions: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS).
4. Select the required safety regulations and electromagnetic compatibility (EMC) certification.
