The difference between pure online UPS and interactive online UPS

1.The difference of circuit structure
Pure online UPS adopts double conversion on-line circuit structure, power input through AC/DC conversion, part of the power to charge the battery, most power converted to alternating current supply load. When the city electricity failure, UPS supply power to the load by the DC/AC conversion. When the UPS fails, it will automatically turn to bypass operation.Online interactive UPS using online interactive circuit structure, the city electrical input through the filter circuit to its surge suppression, filter output to the load, inverter as the charger to charge the battery at this time. When the city electricity failure, Online interactive UPS use the battery power output to the load converted by the DC/AC.

2.The difference of the application
On line interactive UPS provides high quality power protection for servers and network equipment. Pure online UPS in addition to the protection of the server and network equipment, but also for the communication system, automatic control equipment. Pure online UPS can also be compatible with cheap fuel generators.

3.Performance.
Compared with the online interactive UPS, pure online UPS has a higher performance of the voltage output, zero conversion time and a flexible installation of tower and rack converting.
On line interactive UPS using online interactive design, when supply power to the city power supply, the output voltage change with the market city power; when the city power voltage is too high or too low, the UPS start voltage regulation function, when supply power to the battery, the output voltage is sine wave, the default value is 230VAC, the user can choose 220VAC, 240VAC by software. Pure online UPS using pure online design, whether UPS run on city power or battery power, UPS output sine wave, the default value is 230VAC, the user can choose 220VAC and 240VAC by software.

Output voltage accuracy:
When the static state is 1%, while the dynamic state is 5%.
Output voltage distortion:
When the linear load is less than 3%, the nonlinear load is less than 5%.

When online interactive UPS in the city power failure, the battery power supply has a 2~4ms conversion time,while pure online UPS is 0ms.
Pure online UPS using tower frame type converse installation,which is very flexible, it can be installed in tower form. While increase the rack type conversion accessories, can easily converted into a rack mount UPS.

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.

126th Canton Fair

图片
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
