Main features of online interactive UPS

1.Whether online interactive UPS in the normal city power supply, or power supply interruption, both power supply from the battery to the inverter, in the meantime, the power supply to the load is provided by the inverter of the UPS. This basically eliminates the impact of any voltage fluctuations and interference from the city power grid on the load, the realization of the load without interference voltage regulator. At present, the online interactive UPS on the market can achieve regulated power supply to the load, when the voltage range of 180 ~ 250V, the general output voltage stability can reach 220±6.6 V.
2.Online interactive UPS sine wave output waveform distortion coefficient is relatively small. At present, the distortion coefficient of the products sold in the market is less than 3%.
3.When the power supply interruption, the line interactive UPS system can achieve the real uninterrupted power supply to the load. UPS manufacturer found that it is because as long as the internal battery can supply power to the inverter, when the city power is interrupted, online interactive UPS supply power to the load by the inverter as normal. Therefore, the interruption of power supply or not, the UPS does not have any internal conversion action. Therefore, in the process of city power supply switch to the interruption, conversion time of UPS power supply to the load is zero.
4.Compared with the off line UPS, the online interactive UPS has excellent characteristics of output voltage transient. Generally, when the full load to no-load transformation, the output voltage range of 4%.
5.Online interactive UPS generally uses PWM pulse width modulation technology, so the noise is relatively small.

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

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
