The role of UPS for data center and its energy consumption analysis

The power supply of the data center can not be interrupted for a moment, even if only a few seconds interruption may also cause significant data loss or damage to the equipment, and even affect the normal operation of the data center, causing serious economic losses. With the rapid development of information technology and related industries, data center UPS power supply system has become a reliable guarantee for the operation of data center.
With the development of industry and the wide application of computer technology, more and more data centers need to be protected by data center UPS power supply system. For the data center, modular UPS system is not only as a whole product to continue supplying power to the load after power failure, but as a high reliability and high intelligent power supply platform, comprehensive protection for the entire data center, not only can provide the backup time, also can improve the quality of power grid. Therefore, data center UPS as an important peripheral of the computer, plays an important role in the protection of the load, improving the quality of power, and preventing the damage caused by the power grid.
Because UPS for data center is a perennial uninterrupted equipment, improve the efficiency of UPS for data center is the key factor to reduce the energy consumption of the data center. The efficiency of each 1% increase, the annual electricity consumption will be very much. In addition, the heat loss of UPS will also be reduced, air-conditioning system will therefore energy saving. In the analysis of UPS system can be time-consuming, should take full account of the following factors:
1.There is a direct relationship between UPS efficiency and load rate
In general, the efficiency values given in the data center UPS technical parameters are derived from the rated load as well as other suitable system states, which represent the best efficiency that UPS for data center can achieve. However, very few UPS runs under 100% loads. When the load rate is low, the efficiency of UPS will be decreased obviously.
2.The efficiency of UPS system should not only consider the efficiency of the UPS itself
Because of the different topology or technology, different UPS have great difference in system configuration. For example, the UPS with IGBT rectifier, can meet the system requirements without the filter. The 6 pulse rectifier UPS for data center, in order to meet the requirements of the system must be configured filter; online high frequency UPS can meet the power supply voltage requirements without increasing the output transformer, while low frequency UPS must increase the output transformer to meet the voltage requirements. Therefore, in the analysis of the efficiency of UPS system, the overall system efficiency of UPS for data center, including its auxiliary equipment (such as filters, isolation transformers, etc.) should be considered.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

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 ...

How to maximize the efficiency of your UPS

图片
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...
