The main classification of switching power supply

In the switching power supply technology, people the develop the electronic devices, while the development of switching frequency conversion technology to promote the switch power supply with growth rate of over two figures to become light, digital, small, thin, low noise, high reliability and anti interference. Switching power supply can be divided into two major categories: AC/DC and DC/DC.

Miniature low power switching power supply

Switching power supply is becoming more and more popular and miniaturized. Switching power supply will gradually replace all applications of transformers in life. The application of low power micro switching power supply should be firstly reflected in digital display meter, smart meter, mobile phone charger, etc.. At this stage, the state is promoting the construction of smart grid, the demand for power meter greatly improved, switching power supply will gradually replace the transformer in the energy meter above the application.

Reverse type series switching power supply

The difference between reverse type series switching power supply and common series switching power supply is the reverse series voltage switching power supply output voltage is negative; and because the energy storage inductor L only outputs the current to the load when the switch K is switched off, therefore, under the same conditions, the output current of the reverse series switching power supply is smaller than the output current of the common series switching power supply.

SP6U-48200 48V Switching Power Supply Embedded System

1.Constructed with standard 19 inch screen, which has the advantage of wide use.
2.The data center area and the installation cost can be saved due to its small size and the embedded installation.

How to maximize the efficiency of your UPS

1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is 10.

On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In

The development of China electric vehicle charging pile

图片
Now in China, the charging station infrastructure construction is in peak, the attention of the government and enterprises in the charging station professional services is recharge or changing the power of choice, the China charging station integrated services have yet to be developed. 1, charging station successful operation case: China existing two largest most mature electric vehicle charging station is Beijing Olympic Games charging stations in the Shanghai World Expo and charging stations, the two charging stations at present is for electric city bus to provide fast battery replacement service, two charging stations are currently does not belong to the formal business operations, but governmental organizations under the pilot run. After two charging stations in common is dominated by a group of local bus operation, charging station founded and funded by a major national special fund and the place, running electric bus ownership bus group, Beijing Olympic charging station power
