What is the difference between a wall plug and a desktop power adapter?
The power adapter is divided into a wall-mounted power adapter and a desktop power adapter, and the wall-mounted power adapter is also called a wall-mounted power adapter. What is the difference between a desktop and a wall-mounted power adapter? In fact, it can be explained simply that a wall-mount power adapter is a power adapter that can be directly plugged into the board. The desktop power adapter is the power adapter that the main body needs to be placed on the desktop. The difference between a desktop power adapter and a wall-mounted power adapter is that the desktop power adapter requires an AC line to connect to the mains.
Power adapters are widely used in security products, communication products, and small household appliances and consumer electronics. Especially in portable consumer electronics and communication products, they are generally less than 10W, such as smartphones and tablets. -10W power adapter power supply, while computer peripherals, security products, small household appliances products generally use 36W or less power adapters, especially in today's energy-intensive energy conservation and environmental protection, this power segment is the most common products, while notebooks, TVs and other products are generally Use a power adapter below 120W, and more than 100W use the built-in power supply. But there are also external power adapters below 200W. But the number is relatively small.
Generally, the wall-mounted power adapter is mostly used below 36W. This power adapter is characterized by the fact that AC wire is not needed, which saves the cost, saves space, and does not require the storage space of the power supply. Directly plugged into the board, it is also safer. There are a few power adapters below 36W that use the desktop type. This is generally because the product is far away from the AC card or because the power adapter is bulky, the quality is heavy, or The power adapter has a heavy weight on it. For example, a multi-port USB power adapter, in order to avoid the use of the above plugged USB products, resulting in unstable insertion, and a power adapter larger than 36W is not suitable for wall-mounting, because its size and weight are large, so More than 36W is generally desktop.
In the early days, we were much more in contact with linear power supplies. For example, repeaters and single-players used in the last century, the power supply is bulky and bulky. You may also encounter embarrassing situations that fall directly from the top of the board because of the unstable insertion. However, with the development of technology and the increasing energy demand, energy efficiency requirements are increasing. Consumer electronics have high efficiency for power adapters, wide input voltage range requirements, and increased copper, iron and labor costs. Linear transformers are mostly replaced by switching power adapters.
