Ming Wei switching power supply - select POWER SUPPLY precautions?

Ans:

In order to increase the life of POWER SUPPLY, it is recommended to use more than 30% of output power rated models. For example, if the system requires a 100W power supply, it is recommended to select a model with a power output greater than 130W, and so on. This effectively increases the lifetime of POWER SUPPLY. In addition, the operating environment temperature of POWER SUPPLY must be considered, and whether there is additional auxiliary cooling device. If the high ambient temperature POWER SUPPLY is required to reduce the output. Ring temperature derating curve for output power. According to the application needs to select various functions: Protection: Over-voltage protection (OVP), over-temperature protection (OTP), over-load protection (OLP) and so on. Application functions: Signal function (POWER GOOD, POWER FAIL), remote control function, telemetry function, parallel function, etc. Special features: Power Factor Correction (PFC), Uninterrupted Power (UPS). Select the required safety and electromagnetic compatibility (EMC) certification.
