What are the advantages of DC module power supply?(2)


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.

(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 power supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

module combination
(1) Parallel expansion. Connecting the output terminals of the same module in parallel can enhance the output capability, but the output voltage of the parallel modules should be adjusted to be consistent to ensure relative current sharing and avoid unnecessary oscillations. For modules with large current output, the lead resistance can also be carefully designed to achieve the effect of current sharing. The number of modules connected in parallel in this way should not exceed 2. At the same time, if one of the module outputs is faulty, the entire system will not work properly. The parallel expansion connection circuit RL is the load.

(3) The technology is relatively simple, and it is easy to meet the relevant requirements;

(4) DC module power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;

(6)DC module power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

AC-DC power module

 In many fields, switching power supply modules play a role that cannot be ignored and are very important.
