(DC/DC) converter
The DC/DC converter converts a fixed DC voltage into a variable DC voltage. This technology is widely used in the stepless speed change and control of trolleybuses, subway trains, and electric vehicles. Responsive performance, and at the same time receive the effect of saving power. Replacing the varistor with a DC chopper can save power by (20~30)%. The DC chopper can not only play the role of voltage regulation (switching power supply), but also can effectively suppress the harmonic current noise on the grid side.

(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) high-voltage input 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;

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

Regulation of output voltage
For module power products with TRIM or ADJ (adjustable) output pins, the output voltage can be adjusted within a certain range through resistors or potentiometers, and the general adjustment range is ±10%.
For the TRIM output pin, connect the center of the potentiometer to TRIM. In all modules with +S and -S pins, the other two ends are connected to +S and -S respectively. When there is no +S, -S, connect the two ends to the output positive and negative poles of the corresponding main circuit (+S to +Vin, -S to -Vin), and then adjust the potentiometer. The resistance value of the potentiometer is generally more appropriate to use 5 ~ 10kΩ.

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

(6) high-voltage input 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.
