What are the advantages of DC module power supply?(1)

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

The switching power supply module, in short, is to obtain a higher power non-standard customization supply through some modifications. In fact, the internal circuit of the switching power supply module is actually a switching power supply. So, what are the advantages of switching power supply modules? What are its main applications?

1. What are the advantages of switching power supply modules?

There are many advantages of switching power supply modules:

(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 non-standard customization supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
