Ming Wei switching power supply is why use?Ming Wei switch what to use, I see he is a circuit board, five wiring of the mouth, he used in the equipment what is the use? What is his general effect on the equipment?
Equipment and equipment are used within the DC, switching power supply to the 220v AC, DC into the equipment for use.
AC variable DC, high voltage to low voltage for the equipment circuit to do power use.
Regardless of the brand of switching power supply, the function is the same, to the equipment power supply, the general electrical equipment no matter what the external input is 110v or 2200v AC, the internal power are DC, usually with positive and negative 24v, 15v 5v And so on, switching power supply, is the exchange of alternating current into a stable DC for the use of equipment
