What are the advantages of DC module power supply?(2)
(1) It has a particularly wide range of uses, not only aerospace, post and telecommunications, but also metallurgy, mining, automatic control, etc., whether it is social production or daily life, it can be well used;
(2)DC module 24V input power supply The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
(3) The technology is relatively simple, and it is easy to meet the relevant requirements;
(4) DC module 24V input power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;
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.
(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;
(6)DC module 24V input power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;
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.
In many fields, switching 24V input power supply modules play a role that cannot be ignored and are very important.
