The Department of Energy, abbreviated as DOE, has issued DOE certification in accordance with US energy efficiency regulations, which is the source of DOE certification; CEC is the English abbreviation for the California Energy Commission in the United States. On December 30, 2005, CEC issued energy efficiency certification, also known as CEC certification, in accordance with California's electronic and electrical regulations.DOE CertificatePower adapter energy efficiency certificationCertification purposeThe main purpose of issuing DOE certification is to save energy and reduce emissions, help users save electricity, and thus reduce energy consumption demand and greenhouse effect. The latest DOE regulations require all products within the scope of DOE certification to meet the requirements; The main purpose of CEC certification is to improve the efficiency of electronic and electrical products, save energy, and reduce carbon dioxide emissions. CEC certification involves 58 categories...
A low-power plug-in power adapter that can convert 220V voltage into 5V or 12V voltage, suitable for various low-power electronic devices. A low-power wall mounted power adapter is a portable power source that can connect low-power devices to a socket. It has portability and reliability, and can effectively protect your device from power fluctuations.plug-in power adapterThe advantages of low-power plug-in power adaptersThe low-power plug-in power adapter has many advantages. Firstly, it can convert high voltage into low voltage, enabling the use of low voltage devices. Secondly, it can convert alternating current into direct current, allowing for the use of direct current devices. In addition, it can also convert multiple circuits of electricity into single circuit electricity, so that single circuit electrical devices can be used. Finally, it can also convert the power source into other forms of energy, such as thermal energy or light energy.Usage of low-power plug-in power adapterI...
The reason why the laptop power adapter is designed so large is mainly due to the limitations of its internal structure and the development of technology. Modern laptops generally use lithium batteries, and the output voltage of lithium batteries is generally around 10V. In order to fully utilize AC power and convert it into DC power through transformers, laptop power adapters need to convert AC power with a voltage of over 100V into 10V DC power. Therefore, large capacity transformers and capacitors are needed as components. At the same time, in order to ensure continuous and stable power output during use, the adapter also needs to have certain overcurrent, overvoltage, short circuit protection functions, etc., which also leads to an increase in its volume.Upgrade of laptop power adapterAlthough the bulky adapter has brought some inconvenience to lightweight laptops, manufacturers have not stopped working hard to improve this. In recent years, some laptop adapters have become smalle...
With the popularization of electric vehicles(EV), EV charging stations have gradually become a topic of concern for people. However, for ordinary car owners, the knowledge related to EV charging stations is still not comprehensive enough. Today, let's learn some basic knowledge about EV charging stations together.7KW Smart AC EV Charging Station1. Types of EV charging stationsCharging piles can be divided into two types: AC charging piles and DC charging piles. The communication charging station is currently the most widely used charging station, mainly used to provide slow charging services for vehicles, with a general charging power of 3kW~22kW. DC EV charging stations can provide fast charging services for EV, with a general charging power of 50kW~400kW. In contrast, DC EV charging stations have faster charging speeds but are also more expensive and have higher installation costs.2. Standards for EV charging stationsIn order to ensure the compatibility and interoperability of vario...
