What are the advantages of isolated module power supply?(1)
The switching power supply module, in short, is to obtain a higher power dc power supply module 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;
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).
(2) isolated dc power supply module supply The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
