Characteristics of switching power supply:
The manufacturer of Switching power supply 30V tells you that it uses the power circuit to control the switch tube to perform fast on and off, convert the DC power into high-frequency AC and give it to the transformer to perform a DC transformer, thereby forming a necessary set or multiple Operating Voltage. The reason for converting to high-frequency AC is that the efficiency of high-frequency AC in the transformer DC transformer power circuit is much higher than that of 50HZ, so the switching transformer can be made small, and it is not very hot when working, and the cost is very high Low, if you don't turn 50HZ into a high frequency, then switching power supply is meaningless.
The manufacturer of Switching power supply 30V tells you that the switching power supply charging head has a floating charge function, and the working voltage increases as the current decreases.
