The purpose and process of aging testingPower adapter is a common electronic product used to convert different voltages, currents, and other electrical energy to meet the power supply needs of electronic devices. To ensure the quality and stability of the power adapter, aging testing is required. Its purpose is to simulate a more realistic usage environment and load conditions through long-term operation under constant current and voltage conditions, and then detect the quality and performance of the power adapter.6W WALL AC DC ADAPTERThe process of aging testing is usually divided into the following stages:1. Initial aging stage: The power adapter begins to work continuously for a long time, lasting for 24 hours.2. Mid stage aging stage: The duration is between 3-7 days, adjusted according to actual needs.3. End stage aging stage: lasting for 24 hours, test the final performance indicators of the power adapter.The structural composition of the aging cabinetAn aging cabinet is a devic...

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...
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...
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...
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...
