Because for the current industry market, inferior power adapters account for about 30% of the market. It is a big threat to our factories that make high-quality products, because the unit price of power adapters produced with second-hand originals will be 30% or more cheaper than the unit price of our brand-new materials. As a result of the chaos in the current market, some manufacturers are struggling with prices, and quality has not received much attention. It is a big hidden danger for customers and terminal consumers. Computer power adapter
The input voltage adjustment range of the power adapter is the maximum change value of the allowable input mains voltage, generally 90～264V AC, the corresponding range is 90V～132V AC under 110V voltage, and the range is 176V～264V AC under 220V voltage..
In order for the notebook computer to work stably, a stable DC voltage must be provided. This device that provides a stable DC voltage is a DC stabilized power adapter. This DC stabilized power adapter, in addition to providing a stable DC power adapter for the electronic circuit of the notebook computer, is also required to have high reliability, safety and environmental resistance. Computer power adapter
The plug-in type Chinese regulatory certification power adapter switching power supply refers to a power supply that uses modern electronic technology to control the time ratio of the switch tube registration and shutdown. The plug-in type Chinese regulatory certification power adapter maintains a stable output voltage. The switching power supply of the power adapter Generally composed of pulse width modulation (PWM) control IC and MOSFET, advantages: high conversion power, small size, able to operate in a wide voltage range
