What kind of 24V input power supply will be higher(1)

24V input power supply realizes voltage conversion. For example, when the mobile phone is out of power, it needs to be charged, but the 220v voltage cannot be directly used in the mobile phone, which will cause the mobile phone to burn. At this time, a conversion device is needed to convert the voltage that the mobile phone can use. This conversion device is the power module. This article will introduce you what kind of 24V input power supply to choose, which will be more secure?

24V input power supply One: circuit design principle and process

Regulation of output voltage
For module power products with TRIM or ADJ (adjustable) output pins, the output voltage can be adjusted within a certain range through resistors or potentiometers, and the general adjustment range is ±10%.
For the TRIM output pin, connect the center of the potentiometer to TRIM. In all modules with +S and -S pins, the other two ends are connected to +S and -S respectively. When there is no +S, -S, connect the two ends to the output positive and negative poles of the corresponding main circuit (+S to +Vin, -S to -Vin), and then adjust the potentiometer. The resistance value of the potentiometer is generally more appropriate to use 5 ~ 10kΩ.

The quality of the resolution of the circuit schematic is usually done from a professional perspective. This power module can be divided into two kinds of bare board and packaged, according to an intuitive way of bare board, such as electronic components layout is reasonable and orderly, generous, orderly, and the net pad is lit upright. Also, stationary modules will not be able to see what's going on inside, but it's much better not to be exposed due to safety and performance levels. The soldering process can include both wave soldering and manual soldering, and the quality of the mechanized production process of wave soldering is superior to that of manual soldering.
