A data center is a complex set of facilities. It includes not only computer systems and other supporting devices (such as communication and storage systems), but also redundant data communication connections, environmental control devices, monitoring devices, and various security devices.

With the rapid development of the financial industry in recent years, its requirements for information storage and processing capacity are higher and higher. Financial services depend on the management and analysis of information. As a platform to support the application of information, data center will play an increasingly important role. Power supply is the basic guarantee for the normal operation of IT equipment in data center. Once power supply failure occurs in data center, the consequences caused by data loss will be disastrous. Therefore, emergency power supply system is one of the indispensable important equipment in data center.

Rawsun diesel generator system is one of the emergency power sources widely used in data centers. In the event of a municipal power outage, the UPS or HVDC backup battery in the data center enters the discharge mode to maintain the continuity of power supply for IT equipment. At the same time, Rawsun diesel generator sets configured in the data center are quickly started and completed, providing power support for the whole data center. Reasonable distribution of the system determines the equipment uninterrupted power supply safety, reliability, and long – term. In the preliminary design and planning process of the data center, Rawsun diesel generator sets are configured as emergency power supply guarantee according to the capacity introduced by the municipal power outside the data center.
