Liaoning Telecom Data Center is located in the old industrial base in northeast China. It is one of the important big data cloud platforms in the region. It provides high-quality and efficient Internet access, data communication, fixed and mobile phones and other information services for enterprises, institutions and individual users in the region. The concept of green, low-carbon, energy-saving, reliable and safe energy systems in data centers has become a trend. China Telecom Liaoning Branch's bidding for the procurement of distributed energy systems is an important step in response to the country's international commitment to "dual carbon".

The 6KVA AC DPS equipment awarded in this project adopts a "mains+DPS AC" power supply method, and the power module and energy storage module support online replacement. The overall height of a single DPS device is only 3U, which further saves cabinet space and significantly improves the utilization rate of the computer room. Each DPS device is dispersed and deployed in various server racks, without the need for a dedicated power room, saving corresponding civil engineering costs and refrigeration investment. The efficiency of a single DPS system can reach over 95%, effectively meeting the requirements of energy conservation and emission reduction in data centers, while also having higher reliability and security.
