What are the advantages of isolated 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) isolated module 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) isolated module power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

The secondary power DC/DC converter of the communication power supply has been commercialized. The module adopts high-frequency PWM technology, the switching frequency is about 500kHz, and the power density is 5W~20W/in3. With the development of large-scale integrated circuits, the module power supply is required to be miniaturized, so it is necessary to continuously increase the switching frequency and adopt new circuit topologies. The power density of the module power supply has been greatly improved.

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

(3) Before the installation is completed and the power is turned on, the wiring on each terminal should be checked and checked again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values are correct. Prevent the occurrence of reverse and wrong connections.
(4) For high-power power supplies, there are generally two or more "+" output terminals and "-" output terminals. In fact, they belong to the same output electrode, but for the convenience of user wiring, they are connected together internally.
(5) The module power supply is not allowed to work at full load for a long time. The utilization rate of linear power supply should be controlled within 60%; the utilization rate of switching power supply should be controlled within 80%, otherwise it may cause early artificial failure of module power supply.

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

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