What Are Some Important Parameters Of Switching Power Supply?

1.Efficiency: the efficiency of power supply is closely related to the design circuit of mean well power supply. High efficiency meanwell power supply can improve the efficiency of electric energy use and reduce the power consumption and heat generation of power supply to a certain extent.

2.Rated voltage: It is used to calibrate the voltage that can be applied to both ends of the over voltage protector for a long time.

3.Rated power: generally refers to the effective power that can be continuously output; This is the maximum power that can work continuously under normal working conditions. The rated power should be the most important parameter specification of a power supply. If the rated power of the power supply cannot meet your load demand, various unpredictable problems may follow.

4.Input voltage range: That is the PSU allows the variation range of the mains voltage, because the local voltage fluctuation directly affects the operation of the PSU, especially in some areas where the power grid is relatively poor, and the voltage difference between day and night is very large. If the well mean power supply needs to work 24 hours, whether the PSU can work in such a large range of changes is critical.

5.Rated power: generally, we recommend customers not to load at full power, because the power loss on some lines should be considered, so the power consumption should not exceed 80% of the rated power. The specific use should also be determined according to the actual use environment. If the environment is hard, closed, and not conducive to heat dissipation, then the actual power consumption should be discounted.

6.Noise and filtering: this indicator needs to be visually and quantitatively judged by professional instruments. It is mainly that 220V AC is transformed into various low voltage DC through the filtering and stabilizing of switching power supply. Noise marks the smoothness of the output DC. The filtering quality is directly related to the AC component of the output DC, also known as the ripple coefficient. The smaller the coefficient, the better. At the same time, the capacity and quality of the filter capacitor also affect the voltage stability when the current changes greatly.
