· Standard specification requirements for low-temperature aging of power adapters

The purpose and process of low-temperature aging testingDuring the production process of power adapters, after a certain period of use and storage, some components in the adapter circuit may experience aging, thereby affecting the quality and performance of the adapter. To ensure the quality and reliability of the product, it is necessary to conduct low-temperature aging tests on the power adapter.Low temperature aging test is the process of placing the power adapter in a low-temperature environment for long-term startup testing. Normally, the temperature range for low-temperature aging testing is -20 ℃ to -40 ℃, and the testing time is usually 24 to 72 hours. During the testing period, it is necessary to monitor the circuit quality and performance of the power adapter.48W Desktop Power AdapterRequirements for low-temperature aging testing in international standards and industry normsBoth international standards and industry norms have requirements and regulations for low-temperature...

· Why does the power adapter need to undergo aging testing?

1.After the production of the power adapter is completed and before it flows to the market,it will undergo aging testing to ensure product quality. When the power adapter that has undergone aging testing flows into the hands of consumers, there are basically no fault problems. In addition, the lifespan and quality of the power adapter that has undergone aging testing can be guaranteed.Power adapter aging test cabinet2. Power aging belongs to Environmental Stress Screening (ESS), which is a popular quality and reliability assurance method for modern high-tech electronic products. As the name suggests, environmental stress screening is the use of external environmental stress to expose potential defects in electronic hardware caused by weak components and poor processes in the manufacturing process. Then, various appropriate inspection or testing methods are used to identify and remove these defective products, or corrective actions are taken for maintenance, in order to improve the man...

· Detailed explanation of aging standards for power adapters

The significance of aging standardsPower adapter is a crucial component in electronic products, and its quality directly affects the stability and reliability of the product. In order to ensure the quality of power adapters, a series of aging standards have been established. Aging testing can simulate various environmental factors and loads experienced by power adapters during long-term operation, accelerate the aging process, and test the reliability and stability of the adapter in a relatively short period of time.6W WALL AC DC ADAPTERAging testing standardsThe aging test standards vary according to different product types and usage environments, mainly including the following:1. Industrial standards: Industrial standards require products to pass aging tests to ensure product quality. For example, power adapter products can be tested according to standards such as GB/T 4943.1-2011 "Safety of Household and Similar Electrical Appliances - Part 1: General Provisions" and GB/T 9254-2008...

· The main technical indicators of switching power supply

Switching power supplies have the following main technical indicators：500W Switching Power Supply1. Output powerThe output power of a switching power supply refers to the electrical energy it outputs, usually expressed in watts (W). The size of the output power directly determines the range of use of switch mode power supplies, for example, the maximum power of computer power supplies is generally between 300W-1000W. The size of output power can also affect the price and reliability of switching power supplies.2. Output voltageThe output voltage of a switching power supply refers to the magnitude of the voltage output from its output port, usually expressed in volts (V). Different devices and scenarios require different output voltages, for example, laptops need to output a voltage of 19V, while mobile phone chargers need to output a voltage of 5V.3. Output currentThe output current of a switching power supply refers to the magnitude of the current output from its output port, usually...

· Why are there more and more virtual label power supplies in the market?

Recently, many people have reported that they often buy fake label power supplies, which leads to their devices not being able to operate and meet the requirements. While helping to solve the problem of fake labels, I also deeply doubt why there are more and more fake label power supplies on the market?1. Intense market competitionIn this fiercely competitive market environment, some unscrupulous merchants, in order to attract the attention of consumers, are willing to improve the competitiveness of their products by falsely labeling the parameters of the power supply. They take advantage of consumers' lack of knowledge about power supply and intentionally exaggerate the output power, conversion efficiency, and other parameters of the power supply, leading consumers to mistakenly believe that they have purchased a high-performance power supply.2. Cost factorsSome unscrupulous merchants, in order to reduce production costs, use inferior battery cells and circuit designs, resulting in t...
