What are the advantages of DC module power supply?(1)
The switching power supply module, in short, is to obtain a higher power price 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?
rectangular wave of 20 kHz.
Due to the poor working conditions of the welding machine power supply and frequent short-circuit, arcing and open-circuit changes, the working reliability of the high-frequency inverter rectifier welding machine power supply has become the most critical issue and the most concerned issue by users. . The microprocessor is used as the relevant controller of pulse width modulation (PWM), and through the extraction and analysis of multi-parameter and multi-information, the purpose of predicting various working states of the system is achieved, and then the system is adjusted and processed in advance to solve the problem. The reliability of high-power IGBT inverter power supply is improved.
Foreign inverter welding machines can achieve a rated welding current of 300A, a load duration rate of 60%, a full-load voltage of 60~75V, a current adjustment range of 5~300A, and a weight of 29kg.
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;
(2)DC price supply The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
