Cooling technology has developed rapidly in recent years, significantly improving efficiency and reducing energy waste. The energy consumption of the air conditioning in the computer room accounts for 1/3 to half of the total power consumption of the data center. Nevertheless, these measures are not enough. Another key element of data center infrastructure provides similar improvements.
Uninterruptible power supply is an important part of data center operation, providing key power protection and providing reliable backup power when the power interruption occurs. But just as servers consume electricity, generate heat, and require continuous cooling to run safely, so do UPS devices. In the past, this has affected the efficiency of many data centers, but in this field, significant technological advances have been made, that is, the rise of modular UPS systems. Previously, the most deployed UPS power source in the data center was a large tower type device, using traditional technology to achieve the best efficiency only when the workload was 80%-90%. This UPS device tends to be easily deployed at initial installation to provide the necessary redundancy, which means that they often run under low load, it is inefficient and waste a lot of power. In addition, these large tower UPS also draw a lot of heat, so a lot of cooling is needed. However, the UPS power supply has a service life, and the industry’s best practice suggests updating equipment every 7-10 years. Many of the UPS installed and deployed during the boom period of the data center will be replaced when the modern modular UPS is introduced. These UPS power supplies can provide higher efficiency, simple scalability, intelligent control, and system interconnectedness.
The modular UPS system is not a large, inefficient, independent tower type device, but consists of several smaller rack mounted units that are connected in parallel to provide the necessary power and redundancy. Its capacity is closely matched with the load requirements of the user’s data center, and can be easily extended at any time when it is extended, and other modules can also be simply added on the basis of “pay on demand”. Modular UPS does not contain transformers, which itself can provide up to 5% efficiency improvement. Its load curve efficiency is as high as 96%, which is far beyond the function of low power UPS. In theory, running modularized UPS systems in economic mode can even increase their efficiency to 99%, but this performance enhancement requires the key load to face the risk of grid power fluctuations. Modular UPS devices are smaller, lighter, and produce less heat, so there is no need for too much cooling equipment, less space and easier maintenance. In addition, its modular design is “hot plug”, so if there is a module failure or failure, they can be replaced without the power protection system online. This kind of UPS power system is also easy to integrate with the energy management system (EMS) or data center infrastructure management (DCIM) software to help automate the data center. These intelligent UPS devices continuously collect and process running data, which can be used to optimize performance and identify future areas of improvement, which means that the pursuit of maximum efficiency is a continuous process.
By providing higher power density and higher efficiency with smaller area, modularized UPS enables the data center to do much more with less money. In an era of increasing demand for data, overloaded power grids are becoming more and more overwhelmed. This capability will be invaluable. The use of an efficient UPS power can do this while reducing energy costs and reducing carbon emissions.
