Information

China DC power adapter manufacturers said that power adapters are widely used in life, such as mobile phones, LED lights, routers, notebook computers and printers. However, many people are confused when choosing a power adapter. The following China dc power adapter  manufacturers share the three conditions that must be met when choosing a power adapter.

China dc power adapter  manufacturers
1. The interface of the adapter matches the device.
2. The output voltage must be the same as the rated input voltage of the load, or within the voltage range that the load can withstand, otherwise, the load may be burned.
3. The output current of the power adapter should be equal to or greater than the current of the load to provide enough power.
Everyone knows that the power supply has internal resistance, the greater the internal resistance, the greater the loss. China DC power adapter manufacturers will determine the no-load output voltage within a certain range according to the size of the internal resistance when producing the adapter, and the current threshold corresponding to the voltage threshold is the current nominal value we see, and the current nominal value The larger the value, the better the load capacity of the adapter. So choosing an adapter with a slightly higher current will not hurt the battery, but will make charging faster.
China DC power adapter manufacturers said that the correct selection of the power adapter and the correct use will not cause damage to the electronic equipment and will not shorten the normal service life.
