  Power adapters are widely used in routers, phone handsets, game consoles, language repeaters, walkmans, notebooks, mobile phones and other equipment. Most power adapters can automatically detect 100-240V AC (50/60Hz). U.S. 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, and able to operate in a wide voltage range.

  The application of the power adapter in the notebook computer, the semiconductor integrated circuit (IC) used in the notebook computer requires a DC voltage. The DC voltage is used because the IC cannot work under the AC voltage of 50Hz or 60Hz, and the IC will be reversed voltage (reverse bias voltage). )damage. Generally, the fault voltage of the IC is below DC20V (DC5V~10V). The IC can only work stably within the voltage range of the high-power power adapter specified in the product specifications. Therefore, the voltage of the power adapter that supplies the IC must work within the operating range. U.S. 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..

  Power adapters are widely used in security products, communication products, small home appliances and consumer electronics products, especially in portable consumer electronics and communication products, generally within 10W, such as smart phones and tablet computers generally use 5 -10W power adapter for power supply, while computer peripherals, security products, and small home appliances generally use power adapters below 36W, mostly American power adapters

  The materials used in the internal electronic components of the power adapter are roughly divided into three types, the lowest level is used materials or fake materials; the middle level is inferior materials; the highest level is good materials. Generally, copycats will use old and fake materials to replenish the number, and no-brand manufacturers will use better inferior materials, and only first-line brands will use the best quality real materials and good materials. Therefore, the average price of the two 36W power adapters of the same level is 30 yuan better than the cheap product of only 15 yuan.
