3. according to their own purchase needs, determine the choice of bare board power supply manufacturers
Buyers in accordance with their own requirements, after comparing a number of manufacturers, you can according to their own purchase needs, determine the choice of bare board power supply manufacturers, to ensure their own product quality, service quality and price and other factors, to meet their own use requirements, to buy cost-effective products. In order to choose the right manufacturer, the first thing we need to do is to research the market and understand the current situation of bare board power supply manufacturers and their products on the market, including the quality, price, service and the reputation of the manufacturers. This allows us to grasp the market situation of manufacturers, so as to find the right manufacturers. Secondly, we can refer to the evaluation of manufacturers by some experts or industry insiders, such as manufacturers, suppliers, customers, etc. They have a wealth of industry experience, can help us find the right manufacturers, so as to provide us with good quality and service. We also need to understand the background of the manufacturer, look at their R & D strength, production capacity and quality control, so as to determine whether the manufacturer is suitable for our requirements, and whether we can provide the product quality and service we need. According to their own needs, comprehensive consideration of the above aspects of the situation, you can make a suitable choice of manufacturers. Only by grasping the comprehensive and accurate selection of the right manufacturer can we ensure that we can get the right products and services, thereby saving costs and improving efficiency.
Summary: It is very important to choose the right bare board power supply manufacturer. We should start with market research, reference evaluation and understanding the background of the manufacturer, and then make the right choice after comprehensive consideration.

Product selection and application considerations
The design power of each product of our company will have a certain amount of redundant power, which can run for a long time under full load or even over the rated load. However, for the sake of high reliability and prolonging the service life of the power supply, please do not let the load reach the rated value. It is generally recommended to use 60%-80% of the rated load, and the ambient temperature is recommended to be about 30 ℃, which can be fully loaded at an ambient temperature of 55 ℃, but this will undoubtedly greatly reduce the reliability and service life of the product. In actual use, please pay attention to the two factors of controlling load and temperature. If the ambient temperature is relatively high, it is necessary to reduce the load as much as possible (that is, to increase the load margin and select products with greater output power). On the contrary, if a large load current is required, then try to do a good job of ventilation and heat dissipation, such as placing the power supply module in an open space and increasing cooling fans. The specific value is not absolutely fixed. Generally, it is recommended that the load should not exceed 20% of the rated load when the ambient temperature is 55 ℃, which can keep the product very high reliability. Tip: Please use temperature measuring equipment to evaluate the temperature, and do not rely on skin feeling. Short time and a small proportion of full load, high temperature operation, the reliability and life has little effect. For example: each full load lasts less than 1 minute or half a minute, and the interval is more than 10 minutes, while the load during the interval is less than 15% of the rated load, then even if the operation at 55 ℃ is also possible. Safe Use Warning: Since the bare board series does not have a shell, the input is 220V AC at the same time. The input pins and corresponding terminals of the module are directly connected to 220V. Please pay great attention to prevent short circuit between electric shock and metal objects and ensure that the power supply is disconnected before any touch. Load Requirements for 2. Use of Multiple Output Power Supplies Generally, the voltage accuracy of the output of the multi-output power supply is: the nominal value of the main output is plus or minus 1%, and the nominal value of the secondary output is plus or minus 5%-10%. The first output of the multi-output power supply is the main circuit, and the other output is the secondary circuit. The voltage accuracy and carrying capacity of the main circuit are higher than those of the secondary circuit. Therefore, the main circuit with large current and high voltage accuracy requirements should be generally selected, it is appropriate that the ratio of each current is 50-100%, and the secondary circuit must not be loaded separately under the condition of no load on the main circuit, otherwise the secondary circuit voltage is too low to be used normally. In addition, if the main circuit load is full load and the secondary circuit load is light load, the secondary circuit voltage may increase, otherwise the secondary circuit voltage will decrease, and the reliability and service life will have little effect. For example, if each full load lasts less than 1 minute or half a minute, and the interval is more than 10 minutes, while the load during the interval is less than 15% of the rated load, then even operation at 55°C is possible.

Precautions for the use of switching power supply modules
The high-frequency transformer of switching power supply is generally shielded for the first time, which is not described above. Switching power supply is a high-frequency product, PCB component layout for EMI, please pay close attention to this point. If the switching power supply has a mechanical shell, the structure of the shell has a great influence on the radiation, please pay close attention to this point. The parameters of different manufacturers of the main switch tube and the main diode have certain differences, which have certain influence on EMC. Please pay close attention to this point.

Can switching power supply and module power supply be universal?
A module power supply is a power supply that can be mounted directly on a printed circuit board and is characterized by providing power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field programmable gate arrays (FPGAs), and other digital or analog loads. In general, such modules are called point-of-load (POL) power supply systems or point-of-use power supply systems (PUPS).

The difference between switching power supply and module power supply
(1) The difference in use: module power supply, output voltage, remote control switch circuit, input protection circuit. Switching power supply, control the switch tube on and off time ratio, maintain a stable output voltage of a power supply. (2) The difference in composition: Switching power supply: Generally composed of pulse width modulation (PWM) control IC and MOSFET. Module power supply: it is composed of power supply module with a small amount of discrete components.

Loss of switching power module
The loss of high-power module switching power supply mainly includes high-frequency switching loss, high-frequency transformer loss, rectifier loss and line conduction loss. In the application of low voltage and high current output, the rectifier loss and line conduction loss occupy a larger proportion, the lower the output voltage, the greater the output current, the rectifier loss and line conduction loss accounted for the proportion of the total loss of the module switching power supply.
