What are the advantages of high-voltage input module power supply?(2)
For the ADJ output pin, it is divided into input side adjustment and output side adjustment. The output side is adjusted in the same way as the TRIM pin. The input side adjustment can only increase the output voltage. At this time, one end of the potentiometer is connected to the center, and the other end is connected to the ground of the input end.
(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 LED advertising screen 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 LED advertising screen power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;
(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;
Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.
(6) high-voltage input module LED advertising screen power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;
In many fields, switching LED advertising screen power supply modules play a role that cannot be ignored and are very important.
