The advantages and disadvantages of switching power supply!

Advantages of switching power supply: easy to use high-power power centralized power supply, when raw materials such as rising prices, showing a better cost performance. Small size and light weight, to choose from many brands and models.

Disadvantages of switching power supply: if the quality of power supply is not good, high-frequency ripple is not good control, for some access controller with poor anti-interference ability, it is easy to cause the crash of access controller, resulting in the situation of not opening the door.

Note the following points when selecting filters:

1. Define the working frequency and the interference frequency to be suppressed. If the two are very close, a filter with very steep frequency characteristics is needed to separate the two frequencies.

2, ensure that the filter can work reliably under high pressure.

3, filter continuous through the maximum rated current, the temperature rise should be low, to ensure that the rated current continuous work, do not destroy the performance of the filter components.

4, in order to make the filter frequency characteristics and the design value in line with the requirements of the signal source impedance and load impedance connected with it is equal to the value of the design.

5, the filter has a shielding structure, shielding box cover and body to have good electrical contact, the capacitor lead of the filter should be as short as possible, the selection of short lead low inductance through the core capacitance.

For the advantages and disadvantages of switching power supply and how to choose the filter is introduced here, hope to help customers to buy the right products!
