Power adapter, whose English name is power adapter, is mainly used for small electronic equipment and electronic appliances power supply conversion equipment, generally consists of shell, power transformer and rectifier circuit. According to the connection mode, it can be divided into desktop type and wall type. According to the type of output current, it can be divided into AC output type and DC output type. At present, it is widely used in notebook computers

Mobile phones, home it equipment and other equipment.

The normal power adapter is marked with power, input and output voltage, current and other indicators of a nameplate. It is worth noting

The input voltage range. Generally speaking, the power adapter with input voltage of 110v-240v can be used worldwide and suitable for all countries and regions. Shenzhen Zhenhuan Electronic Co., Ltd. is committed to design, R & D, production, sales and service

As one of the power supply manufacturing enterprises. Professional design and production of security monitoring power supply and other switching power supply, including outdoor three prevention power supply

Source, conventional switching power supply, power adapter, etc. Input voltage of power adapter produced by Shenzhen Zhenhuan Electronic Co., Ltd

For 110v-240v, international general, welcome to purchase.

In reality, most of the power adapter we come into contact with is switching power supply. Switching power supply refers to through modern electronic technology, control on

Turn off the time ratio of on and off, maintain a stable output voltage of a power supply, power adapter switching power supply is general

It is composed of pulse width modulation (PWM) control IC and MOSFET. It has the advantages of high conversion efficiency, small volume and wide voltage range. Deficiency: it is difficult to maintain when the fault occurs, and the power circuit is greatly disturbed.
