Compared to large data centers, the structure of medium and small data centers is similar. Most of the equipment is also critical loads and requires very high reliability. The redundant rate may not be as high as in large data centers, so the power reliability will have to rely on the power supply itself. Besides reliability, flexibility is one of the most important requirements because of the power upgrading possibility.
1. High-power UPS system
2. Power distribution unit
3. Battery banks
4. Telecom DC power system
5. Monitoring system
Figure 1 shows medium and small data centers. Precision power supply systems, air conditioning systems, and monitoring systems are the main parts of the infrastructure. According to the exact requirements of different projects, UPS paralleling system or a single unit can be the choice.

The power source from the utility and the generator is controlled by the ATS (automatic transfer switch) and connected to the central PDU (Power distribution unit). ATS will choose one of the sources to feed the connected equipment according to utility conditions and custom settings. UPS, telecom DC power supply, and other equipment are connected to the central PDU. According to the requirements of different projects, people can choose a central UPS power source or distributed UPS power source. Central UPS configuration usually applies one high-power UPS system to feed all the critical loads, and distributed UPS configuration applies several UPSs for different kinds of loads.
The advantage of central UPS configuration is that the UPS and the battery banks are installed together, easy for management and maintenance, the disadvantage is that the power distribution is not flexible. In the case of distributed UPS configuration, the power distribution is flexible and people can choose different kinds of UPS for different loads, but the management and maintenance of the system is complex.
We offer the customer reliable and flexible solutions for data center applications. In the case of central UPS configuration, we recommend the modular UPS due to the upgrading requirements. If people choose distributed UPS configuration, we recommend the tower UPS for the fixed loads and modular UPS for the growing loads.
