• How to use the power adapter reasonably

  2022 / 08 / 05

  So how do we use the power adapter reasonably? (1) Prevent the power adapter from being used in a humid environment and prevent water from entering. Even if you put the power adapter on a table or on the ground, be careful not to put wet objects such as drinking glasses around to avoid getting the adapter wet. (2) Avoid using the power adapter in a high temperature environment. In a high temperature environment, many people only pay attention to the heat dissipation of electronic equipment, and often ignore the heat dissipation of the power adapter. In fact, many power adapters generate as much heat as electronic devices such as laptops, phones, and tablets. When in use, the power adapter can be installed in a place that is not exposed to direct sunlight or in a well-ventilated place, and a fan can be used for auxiliary convection heat dissipation. At the same time, the adapter can be turned over, and a small object can be inserted between the adapter and the contact surface to increase the contact surface of the adapter with the surrounding air, enhance airflow, and dissipate heat faster. (3) Use the corresponding power adapter. If you need to replace the original power adapter, you must choose a product that matches the original model. If an adapter that does not meet the specifications and model is used, there may be no problems in a short time, but due to differences in

• Why does the power adapter cause noise interference?

  2022 / 07 / 09

  Power adapters are very common in daily life, and of course there are some common problems, such as noise interference in the adapter. Shenzhen Waweis Technology Co., Ltd. is a professional power supply adapter manufacturer. Let's analyze the power supply for you. Why does the adapter have noise interference: 1. Suppress the EMI generated by the power supply itself; 2. Prevent external electromagnetic noise from interfering with the work of the load of the power supply; 3. Suppresses EMI generated by other equipment and propagated through the power supply. 4. Prevent external electromagnetic noise from interfering with the work of the control circuit of the power supply equipment itself; In addition to the drive circuit, the switching power supply also has a protection circuit, a program circuit, an input and output level detection circuit, etc., and the circuit is quite complex. These circuits are mainly composed of dedicated or general-purpose power supply integrated circuits. An effective way to prevent these circuits from malfuncti

• The specific analysis and treatment method of power adapter failure

  2022 / 07 / 09

  Nowadays, the power adapter has been integrated into our daily life and work. We use it everywhere. If we use it more, there will naturally be problems like this. Today, the editor will introduce the specific analysis and processing methods of the power adapter failure. As follows: Now computers generally use ATX power adapters. When the system fails, a comprehensive analysis should be carried out from the aspects of BIOS, the power adapter itself and the motherboard. According to the principle of "soft first and then hard" in computer maintenance, first check whether the BIOS settings are correct, and eliminate false faults caused by improper settings; the second step, check whether the ATX power supply is normal; the third step, check whether the motherboard power supply monitoring circuit normal. At the same time, when judging whether the power adapter is normal, you can remove the power supply and use a scrapped device (such as hard disk, etc.) as a false load to avoid no-load protection. Connect a 100-150Ω resistor between the PS-ON signal line (green) and the ground line to make the signal low. If the power supply can work, the fault is in the motherboard or BIOS settings, otherwise the fault is in the power supply itself. The power adapter plays the role of the source of power in the computer system. Whether it works normally or not is the key prerequisite for the normal operation of the entire computer system. However, in the routine maintenance process of the computer room, it is found that the power adapt
