Some little knowledge about 12V2A power adapter


The so-called 12V2A power adapter means that its standard voltage is 12v, and its standard current is 2A, which means that its maximum output voltage is stable at about 12V, and its maximum output current is stable at about 2A.

The so-called 12V2A power adapter means that its standard voltage is 12v, and its standard current is 2A, which means that its maximum output voltage is stable at about 12V, and its maximum output current is stable at about 2A, but the actual voltage and current are often higher. However, this does not affect its normal work.

The 12V2A power adapter manufacturer tells you that the power adapter is a small power supply conversion device, which is mainly composed of three parts: a plastic shell, a power transformer and a rectifier circuit. Because of the characteristics of electrical power supply, it is widely used in game consoles, language repeaters, walkmans, notebook computers and other equipment. In life, power adapters are more and more popular and popular among consumers because of their small size, light weight, easy portability, and short-circuit protection.
12V2A power adapter is a power exchange device, we should also pay attention to its precautions when using it, such as what is its nominal voltage, that is, what is the upper limit of the output voltage of the power supply? There is also a power supply with the same nominal voltage Adapters have different output currents, can they be used on the same electrical device? These are the things we should pay attention to when using power adapters. In fact, an active voltage regulator is used inside the power adapter, so even if the circuit voltage fluctuates, its output value is constant.
The 12V2A power adapter manufacturer tells you that the second is that the voltage of the power adapter is the same, the output current is different, and whether it can be used on the same device. The basic principle is that a large nominal current can replace a small nominal current. That is to say, a power adapter with a large output current can be used on the same electrical device instead of a power adapter with a small output current. This does not contradict our principles of electricity.
