What are the advantages of DC module power supply?(2)
Inverter module power supply
High frequency inverter rectifier welding machine power supply is a new type of welding machine power supply with high performance, high efficiency and material saving, which represents the development direction of current welding machine power supply. Due to the commercialization of IGBT large-capacity modules, this power supply has a broader application prospect.
Most of the inverter welding machine power supply adopts the method of AC-DC-AC-DC (AC-DC-AC-DC) conversion. The 50Hz alternating current is converted into direct current by full-bridge rectification, and the PWM high-frequency conversion part composed of IGBT inverts the direct current into a high-frequency
(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 LED advertising screen power supply The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
Distributed Power Supply System
The distributed power supply system uses low-power modules and large-scale control integrated circuits as basic components, and uses the latest theoretical and technological achievements to form a building block-type, intelligent high-power power supply, so that the strong and weak currents are closely combined and the high power is reduced. Components, high-power devices (centralized) development pressure, improve production efficiency.
(3) The technology is relatively simple, and it is easy to meet the relevant requirements;
(4) DC 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;
(6)DC 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.
