Advantages of linear power supply: stable performance, no interference such as high-frequency ripple.

Disadvantages of linear power supply: heat generation and low power utilization. There is no ultra-high power power supply to choose from.

Advantages of switching power supply: convenient for using high-power power supply to concentrate power supply, showing better cost performance when raw materials and other prices continue to rise. Small size and light weight, with many brands and types to choose from.

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