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 24V input 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 24V input power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

input protection circuit
General module power products have built-in filters, which can meet the requirements of general power supply applications. If a more demanding power system is required, an input filter network should be added. An LC or π-type network can be used, but care should be taken to choose a smaller inductance and larger capacitance as much as possible.
In order to prevent the transient high voltage of the input power supply from damaging the power supply of the module, it is recommended that the user connect a transient absorption diode at the input end and use it with a fuse to ensure that the module is within a safe input voltage range. In order to reduce common-mode noise, Y (Cy) capacitors can be added, and a few nf high-frequency capacitors are generally selected. R is a fuse, D1 is a protection diode, and D2 is a transient absorption diode (P6KE series).

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

Internationally, the inverter power supply series products below 400kVA have come out. In the early 1980s, Toshiba Corporation of Japan was the first to apply AC variable frequency speed regulation technology to air conditioners. By 1997, its share had reached more than 70% of Japan's household air conditioners. Inverter air conditioners have the advantages of comfort and energy saving. In the early 1990s, domestic research on inverter air conditioners began. In 1996, the production line was introduced to produce inverter air conditioners, which gradually formed a hot spot for inverter air conditioner development and production. A climax is expected around 2000. In addition to the variable frequency power supply, the inverter air conditioner also requires a compressor motor suitable for variable frequency speed regulation. Optimizing the control strategy and selecting functional components are the further development direction of the inverter power supply for air conditioners.

(6)DC module 24V input power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

 In many fields, switching 24V input power supply modules play a role that cannot be ignored and are very important.
