(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;

reasonable core structure and compact structure.
At the same time, in order to reduce the size of the module switching power supply, the switching frequency of the module switching power supply should be increased as much as possible. If it is to be increased to about 500kHz or higher, the loss of the ordinary magnetic core material is very large, and the magnetic core is easily overheated and magnetically saturated, and even It cannot work normally, so the high-frequency magnetic core material with excellent magnetic properties must be selected in the module switching power supply.

Ring current backup
The ring current generator is mainly used in the telephone exchange exchange to provide ringing to the telephone users, and is generally used in a biased state. Bias can be divided into positive bias and negative bias. In order to improve the reliability of the ring current system, the ring current needs to be backed up. Installation and maintenance of module power supply
Since the types, series and specifications of the modular power supplies produced by various companies are difficult to count, their functional characteristics and physical characteristics are not the same, so they are also different in installation, use and maintenance, but the following aspects should be paid attention to

(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;

power supply module

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