The development of society and the strength of science and technology are in order to facilitate people's life needs. Various types of electronic devices frequently appear in people's lives. The power adapter is the most familiar accessory. However, with the increasing frequency of equipment replacement, many people’s homes, especially those of digital madmen, are simply "piling up" of discarded power adapters. This phenomenon has attracted the attention of the International Telecommunication Union (ITU), and related standards will be issued soon, which deserves the attention of the industry. 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, and able to operate in a wide voltage range.
The external power adapter is more flexible to use. As long as the parameters required by the device can be met, the same adapter can be used. However, in order to ensure the normal operation of the equipment, you must choose a power adapter produced by a regular manufacturer. Computer power adapter
The input voltage frequency is the frequency range within which the power adapter can automatically track the mains and maintain synchronization. Generally, the standard frequency of the power grid is 50Hz or 60Hz, and the power adapter allows the mains frequency to have a certain range of change, which is the input voltage frequency range.
