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 LED advertising screen 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 LED advertising screen 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;
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.
(6)DC module LED advertising screen power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;
The distributed power supply mode has the advantages of energy saving, reliability, high efficiency, economy and easy maintenance. It has been gradually adopted by large-scale computers, communication equipment, aerospace, industrial control and other systems, and is also the most ideal power supply method for low-voltage power supply (3.3V) of ultra-high-speed integrated circuits. In high-power occasions, such as electroplating, electrolytic power supply, electric locomotive traction power supply, intermediate frequency induction heating power supply, motor drive power supply and other fields also have broad application prospects.
In many fields, switching LED advertising screen power supply modules play a role that cannot be ignored and are very important.
