DC switching power supply is a power supply device that converts alternating current into direct current. It rectifies, filters and transforms alternating current, and outputs voltage and current stably as direct current. The DC switching power supply adopts an integrated design, has the advantages of small size, high efficiency, and low noise, and is widely used in various electronic equipment.

The DC switching power supply is characterized by good stability, high reliability, high power density and protection measures. It can adapt to different voltage and current requirements, making it applicable in more complex circuit systems. At the same time, with the development of science and technology, the energy efficiency of DC switching power supply has been greatly improved, which can provide more economical and environmentally friendly power supply options.

In modern society, people cannot do without electricity in their life and work, and DC switching power supply, as an efficient power supply device, provides guarantee for people's life and work. From household appliances to automation equipment in industrial production, DC switching power supplies have a wide range of applications. With the continuous upgrading of technology, DC switching power supply will continue to play its benefits and play an increasingly important role.

Switching power supplies and power adapters, both power supplies used to convert alternating current to direct current to power electronic devices, share some similarities, but also some important differences.

First of all, switching power supplies are usually more powerful than power adapters, ranging from a few watts to hundreds of watts. Switching power supplies are mainly used in household, commercial and industrial equipment such as TVs, monitors, computers, etc. The power of the power adapter is relatively small, usually between 10-100W, and is mainly used for mobile devices, electronic toys, smart home devices, etc.

Secondly, the switching power supply has a wider operating temperature range and can work normally at higher and lower temperatures, while the power adapter has a narrow operating temperature range and can only work normally in a relatively warm environment.

Plus, switching power supplies are often more efficient, meaning they waste less power and generate less heat while powering devices. The power adapter is less efficient and generates more heat during use.

Finally, switching power supplies are usually more expensive than power adapters, but due to their higher efficiency and wider application range, they can save electricity and maintenance costs in long-term use.

In general, although switching power supplies and power adapters have similar functions, there are great differences in terms of power, operating temperature, efficiency, and price. Reasonable selection of a power supply suitable for your own equipment can not only improve the stability and life of the equipment, but also save costs and energy for users.

1. Select an appropriate installation location. The installation location of the bare-board switching power supply should be in a well-ventilated, dry, dust-proof, and corrosion-resistant place, avoiding direct sunlight, high temperature and humid environment. If it needs to be installed in the chassis or other equipment, it should be isolated from other components and an appropriate heat dissipation space should be reserved.

2. Follow the correct connection method during installation. The bare board switching power supply generally includes an input (AC) terminal and an output (DC) terminal, and the input and output lines need to be connected correctly during installation. The input line should conform to the voltage and frequency of the actual power grid, and at the same time, pay attention to the positive and negative poles, and do not reverse the grounding; the output line should conform to the voltage and current requirements of the peripherals, and also pay attention to the correct polarity. For some special types of bare-board switching power supplies, such as emergency power supplies with protection functions, or switching power supplies with multi-voltage output, the installation and connection methods may be different, so you need to read the product manual carefully.

3. Ensure stable input power. The performance and lifetime of bare board switching power supply are closely related to the stability of its input power supply. Therefore, in the process of installing a bare-board switching power supply, it is necessary to ensure that the voltage fluctuation of the input power supply is within the rated range of the product. If the input power fluctuation is too large, it may cause a short-term power failure of the switching power supply, or even damage the switching power supply.

4. Reasonable selection of cooling equipment. The bare-board switching power supply will generate heat during normal operation, and reasonable heat dissipation equipment is required to help dissipate heat so as not to affect normal operation. When selecting heat dissipation equipment, it is necessary to refer to the parameters such as heat dissipation power and heat dissipation area given in the product manual, and adopt a suitable heat dissipation method to ensure the normal operation of the switching power supply.

First of all, when purchasing a bare board switching power supply, pay attention to the power size and quality issues. The power level should be selected according to the power demand of the electrical appliance, and at the same time, the quality should be ensured to avoid potential safety hazards during use.

Next, pay attention to the use environment of the bare board switching power supply. The bare board switching power supply should be placed in a well-ventilated, dry and clean environment when in use, and try to avoid prolonged exposure to humid, high temperature, and dusty environments to prevent damage to the power supply equipment.

When using a bare board switching power supply, attention must be paid to the correct wiring method. When wiring, you should carefully read the manual of the power supply equipment, and perform wiring according to the relevant instructions in the manual. Pay attention to the correctness of the wiring position, and whether the material, cross section and length of the wire meet the requirements.

In addition, during use, attention should also be paid to the maintenance of the bare board switching power supply. Frequently check whether the connection of the power supply equipment is in good condition, clean up the dust, and ensure good heat dissipation. When using it outside, choose a shell with sunshade and rainproof functions, and clean it regularly.
