AC DC 12V 20A 240W switching power supply

About switching power supply:

Because the core size of the transformer is inversely proportional to the square of the operating frequency of the switching power supply, the higher the frequency, the smaller the core. In this way, the transformer can be greatly reduced, and the power source can be reduced in weight and volume. And because it directly controls DC, the efficiency of this power supply is much higher than that of a linear power supply. This saves energy, so it is favored by people. But it also has disadvantages, that is, the circuit is complicated, maintenance is difficult, and the pollution to the circuit is serious. The power supply is noisy and is not suitable for some low noise circuits.
