Issue Time:2006-09-15
The use of switching power adapter, power adapter I believe many people know how to use it, the power adapter is not only used in notebooks, but also can be used in security monitoring, LED lights, and so on, all use power adapters, power adapters One of the chargers, many people will mix the charger and the adapter, but in fact there is a difference between the two, we have talked about the difference between the charger and the adapter, we can refer to it. The power adapter is a small power supply conversion device, which is mostly used in portable electronic devices or electronic appliances. So what is the use of the power adapter?

The role of the power adapter:
Power adapters are required for our common gaming consoles, Walkmans, laptops, mobile phones, and more. In simple terms, the power adapter is the function of voltage transformation, that is, the high voltage of the visual AC is rectified and transformed by the power adapter to be converted into a low-voltage DC power. For example, input: 100-240VAC50-60HZ output: 12VDC1A Convert high voltage 100-240V to low voltage 12V.

Generally speaking, there is a nameplate on the power adapter. The following points indicate the power, output voltage and current amount. Special attention should be paid to the range of output voltage. If the mains voltage is only 100V, this feature is very effective. . It can be said that the function of the power adapter is to convert the voltage and current functions.

The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It connects the power supply externally and connects to the host computer by a line. This can reduce the size and weight of the mainframe. Only a very small number of devices and electrical appliances are built into the mainframe. Inside. The main function of the power adapter is to convert the voltage and current to make the equipment reach the safe range.
