Five basic functions of notebook power adapters.adapter wholesaler

　　With the gradual introduction of notebook computers into our lives, notebook power adapters, as an indispensable and important component, have gradually become the focus of electronic engineers in the research and development of new products in recent years. In the process of modularization, integration and miniaturization of the power adapter, no matter how its appearance and function have changed, the five basic functions of a qualified notebook computer power adapter itself are the key to whether it can pass the qualified Validation key. Let's take a look at the five basic functions that a qualified power adapter should have.

　　For a laptop power adapter, the most basic and most important job function it has is the ability to adjust the input and output voltages. According to the current international general standards, a qualified notebook computer power adapter product can cope with the voltage range of 100V-240V, that is, no matter where the user is, the notebook computer can be plug and play. A power converter is required. Only by meeting this design requirement can new products meet export production standards.

　　Another thing that the laptop power adapter needs to guarantee is that the voltage output by itself is based on the size and capacity of the laptop. This value is generally selected in the range of several amperes to tens of amperes, but the specifications are still in accordance with The larger the screen, the more power it consumes. This is the main reason why different types of notebooks cannot mix power adapters.

　　In the research and development process of new products, there is another function that is necessary for notebook power adapters, that is, it can play a role in protecting computer components. If there is no power adapter, plugging the notebook directly into the socket will burn the original and the battery. The main reason is the load and other problems. The notebook computer power adapter can control the current within the power load required by the notebook, which can ensure that it is in In the process of normal use, there is no safety hazard due to the power load.

　　The fourth basic function that requires a laptop power adapter is to provide protection for the laptop's battery. A new type of adapter product that has passed the test and certification, can shunt and stabilize the input voltage, filter impurities and clutter in the current, provide stable voltage power to the battery, and can also solve problems such as sudden power failure and reverse inflow of the battery voltage. Bearing down, fully guarantee the service life of its battery. At the same time, during use, the power adapter will also send current to the machine for use and battery charging by default. After the battery is fully charged, it will send a signal to the adapter through the charging current control device to form a power outage, which is also one of the functions of its power adapter. one.

　　The last important function, which is necessary for any laptop power adapter that has passed the ccc certification, is to help the laptop cool down through its own cooling design, so that the hardware will not be cooled due to sudden power failure or other problems. The resulting safety accident can also make it more convenient for notebook computers to use the current provided in terms of voltage regulation.
