power supply module

For the TRIM output pin, the center of the output potentiometer and the center TRIM are all connected to +S, -S in the pin module, and the other two ends are connected to +S, -S respectively. There is no +S, and the -S ends receive the positive and negative outputs of the corresponding main circuit respectively (+S is connected to +Vin, -S is connected to -Vin), and then adjust the potentiometer. The resistance of the potentiometer is generally 5~10kΩ.

the 110 v input LED advertising screen power supply The ADJ output pins are divided into input adjustment and output adjustment. Output trim and output trim. The adjustment method of the TRIM pin is the same. When one end of the potentiometer is connected to the center, the output voltage can only increase the output voltage, and the other end is connected to the ground of the input.

The application of module power supply in several aspects
1. Electricity, mainly integrators and meters and smart meters
2. Industrial control, industrial control field
3. Medical, medical equipment, mainly including tire protectors, monitors, etc.
4. Military industry, the military industry is a widely used aspect.

Input protection circuit General high voltage input module LED advertising screen power supply supply products use built-in filters, which can meet the requirements of general LED advertising screen power supply applications. If a more demanding power system is required, the 110 v input LED advertising screen power supply the input filter network should be added. Either LC or π can be used but care should be taken to choose a smaller inductance and larger capacitance.
