Several common and highly used power adapters

Power adapter as an important part of electronic equipment, its function is to convert one form of power supply into another form of power supply, in order to meet the operating needs of the equipment. The most common AC/DC Power Adapter in daily life works by converting alternating current into direct current required by the equipment.

Wall Mount Power Adapter

The working principle of the wall mount power adapter is to convert alternating current into direct current. wall mount power supply is usually installed on the wall or plugged directly into the board, which can save space and keep it clean, so it can also be called wall plug power.

Different national standard plugs：

 Main features of wall power adapter:

1) Space saving: Its wall-mounted design allows it to be mounted directly on the wall, effectively utilizing the space and reducing the clutter of the use area.

2) Neat and beautiful, easy to carry: the wall-mounted design is small and easy to carry; It can be fixed on the wall to save space and make the space look more neat and beautiful.

3) Simple structure, easy installation: the design of the wall-mounted power adapter is simple, the installation steps are simple and clear, and customers can complete the installation according to the installation steps and tools.

4) High safety: the wall-mounted design greatly reduces a series of safety problems that may be caused by the exposure of the wire.

5) Widely used in various scenarios: Suitable for electronic devices in office environments, such as mice, printers, etc.; as well as small household appliances, cameras, electric fans, routers, etc., including but not limited to these scenarios. Wall-mounted power adapters have been widely adopted.

Desktop Power Adapter

The desktop power adapter is also a power device that converts alternating current into stable direct current required by the device. Because of its large size, desktop power adapter is usually designed to be placed independently on the desktop, rather than plugged directly into a wall  outlet.

Main features of power adapter for desktop:

1) Strong compatibility: With a variety of output voltage ranges, it can adapt to the needs of various equipment while supporting different output power supplies and currents.

2) High conversion rate: The desktop power adapter uses an efficient circuit design,which can effectively reduce energy loss and improve conversion effciency.

3) High efficiency:  The desktop power supply adopts switching power supply technology and efficient circuit design, which has the advantages of high effciency, low heating and good stability.

4) Energy saving and environmental protection: The desktop power supply has intelligent energy saving function, which can automatically adjust the output power according to the different needs of the equipment to reduce energy consumption.

5) Safe and reliable: The desktop power supply has a variety of safety protection, such as over current protection, over voltage protection, short circuit protection, overheating protection and other multiple safety protection functions to ensure safe and reliable use.

Industrial Power Supply & Switch Power Supply

The full name of switch power supply is Switch Mode Power Supply, referred to as SMPS. Its working principle is mainly based on high-frequency switching technology, by controlling the switching tube opening and closing time ratio, maintain a stable output voltage power supply, is also a high-frequency power conversion equipment. A device that converts direct current with fixed voltage or frequency into alternating current with variable voltage or frequency. The switch-mode power supply is mainly composed of main circuit, control circuit, detection circuit and auxiliary power supply.

Main advantages of switching power supply:

1) High efficiency: The switching power supply is much more efficient than the traditional linear power supply.The linear power supply mainly stabilizes the output voltage by adjusting the tube to work in the linear amplifying area, which has low efficiency.

The switching power supply adjusts the output voltage or current by adjusting the switching on and off state of the switch through high frequency switching action, which makes it lose less in the energy conversion process, so the efficiency is high.

2) Small size and light weight: Due to the high operating frequency of the switching power supply and the use of high-frequency switching technology, smaller energy storage components and transformers can be used, thus reducing the overall size and weight of the device. This is a very important advantage for modern electronic devices to pursue the trend of miniaturization and lightweight.

3) High stability and reliability; The switching power supply adopts advanced control technology and protection circuit, which can maintain stable output in various harsh working environments, and has a variety of protection functions such as overcurrent protection, overvoltage protection, short circuit protection, which greatly improves its reliability.

4) Wide range of input voltage adaptability: The switching power supply design has a wide input voltage adaptation range, can adapt to a wide input voltage range, whether unstable mains or other power input, can output stable voltage through the internal adjustment mechanism. So this makes switching power supply can be used in different countries, regions and different application scenarios, without additional voltage conversion equipment.
