Pakistan the switching frequency of the AC-DC switching power supply module?(1)

What is the operating frequency of Pakistan the AC-DC switching LED advertising screen power supply module? What factors need to be considered when choosing an AC-DC switching LED advertising screen power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.

For the ADJ output pin, it is divided into input side adjustment and output side adjustment. The output side is adjusted in the same way as the TRIM pin. The input side adjustment can only increase the output voltage. At this time, one end of the potentiometer is connected to the center, and the other end is connected to the ground of the input end.

Pakistan Choosing the switching frequency of the LED advertising screen power supply does not mean choosing the switching frequency of the LED advertising screen power supply with a good switching frequency, but the choice is suitable for your own use. Most of the current market is like this. The frequency of the AC-DC switching LED advertising screen power supply module is between 50K and 135K, and this frequency range can meet most applications. Let's discuss it. Some of the problems that AC-DC encounters when choosing switching frequency:
