(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;

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.

(2) isolated module 48V 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;

power supply module

(4) isolated module 48V input power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

Remote control switch circuit
The remote control switch operation of the module power supply is carried out through the REM terminal. There are two general control methods:
(1) REM is connected to -VIN (reference ground), the remote control is turned off, and VREF<0.4V is required. REM is suspended or connected to +VIN, the module works, and VREM>1V is required.
(2) REM is connected to VIN, the remote control is turned off, and VREM<0.4V is required. REM is connected to +VIN, the module works, VREM>1V is required. REM is suspended, and the remote control is turned off, that is, the so-called "suspended shutdown" (-R).
If the control is to be isolated from the input, an optocoupler can be used to pass the control signal

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

(6) isolated module 48V 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 48V input power supply modules play a role that cannot be ignored and are very important.
