The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It puts the power supply externally and connects to the host with a line, which can reduce the size and weight of the host. Only a few devices and electrical appliances have the power supply built in the host. Inside. 24V power adapter
Since the inside of the power adapter is a switching power supply that works under high voltage and high current, the workload is relatively heavy, and it is a fully enclosed structure. There is no heat dissipation hole on the shell and no internal fan to assist heat dissipation. Therefore, the power adapter is working The internal temperature is high. In the hot summer, you can feel hot to touch the surface with your hands, and the internal temperature is even higher. Therefore, it must be properly maintained and maintained during daily office and entertainment.
The difference between desktop and wall-mounted power adapters? In fact, it can be simply explained. The wall-mounted power adapter is the power adapter that the main body can be directly plugged into the plug-in board. The desktop power adapter is the power adapter that the body needs to be placed on the desktop. The difference between the desktop power adapter and the wall-mounted power adapter is that the desktop power adapter requires an AC cord to be connected to the mains. 24V power adapter
The characteristics of the switching power supply are: high-speed pass and cut-off with a circuit-controlled switch tube. The direct current is converted into high-frequency alternating current and supplied to the transformer for transformation. The wall-mounted Chinese-standard certified power adapter then generates the required set Or multiple sets of voltage! Plug-in type Chinese-standard certified power adapter and it is not very hot during operation!! The cost is very low. If the 50HZ is not changed to high frequency, the switching power supply is meaningless
Input voltage range: It is the range of the mains voltage allowed by the power adapter, and it is also the mains voltage range that guarantees the normal power supply of the power adapter. The larger the range, the better the adaptability. The input voltage range should be AC 100～240V, special reminder: it It is divided into working conditions under two voltage environments of AC 110V and AC 220V. The correct test method is to switch the voltage test when the power adapter stops working.
