Power Supply with PFC Function

500W Single Output Power Supply with PFC Function SP-500 series can improve the utilization of power to the mains when AC is converted to DC, but it can not reduce the power loss during the conversion process, nor does it save energy. In addition, the PFC can also reduce the interference of the power supply to the mains grid, especially to avoid the impact on other appliances during sudden start-up.

FAQ

Q: How to select the switching power supply?

A: In order to increase the life of the power supply, it is recommended to use models with 30% more output power rating. For example, if the system needs a 100w power supply, it is recommended to select a model with an output power rating greater than 130W. 

In addition, it is necessary to consider the working environment temperature of the power supply, and whether there is additional auxiliary heat dissipation equipment, and the excessively high temperature of the ring temperature power supply needs to be deducted. The derating curve of the ring temperature to the output power.

Q: Why does the power supply crash when it is in use, can it be turned back on and can be operated again?

A: Generally, there are two reasons for the failure of the power supply. First, the load is overloaded to cause overload protection. It is recommended to increase the output power of the power supply or modify the overload design. The second is that the temperature rise is too high and temperature protection occurs. All of the above situations will cause the power supply to crash due to entering the protection state, and the status will be restored after the status is released.
