power supply 500w 600w
When the voltage and current ratings of the power switch tubes are the same, the output power of the converter is usually proportional to the number of switch tubes used. Therefore, the greater the number of switch tubes, the greater the output power of the DC/DC converter. The output power of the four-tube type is twice that of the two-tube type, and the output power of the single-tube type is only 1/4 of the four-tube type.

Description
Switching power supplies are becoming popular and miniaturized. Switching power supplies will gradually replace transformers in all applications in life. The application of low-power micro switching power supplies should first be reflected in digital display meters, smart meters, mobile phone chargers, etc. At this stage, the country is vigorously promoting the construction of smart grids, and the requirements for electric energy meters have increased significantly. Switching power supplies will gradually replace the application of transformers in electric energy meters.
