Due to the fast increasing requirement of information management in all kinds of industries, people are building more and more large data centers all around the world. Usually the large data center is bigger than 500 m2 and the numbers of racks inside is a large number. The requirements for power system include high power, high reliability, easy for upgrading and etc.
Figure 1 shows a sample diagram of large data center. The main infrastructure includes UPS, PDUs, air conditioners, DC power, lightning protection, monitoring system and etc. Due to the high reliability requirement, large data centers are usually built according to Tier4.
Figure Figure 1: Magnizon solution for large data center
Figure 1 shows Magnizon Power Systems solution for large data center. The power source from the utility and the generator are fed 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 equipments according to utility condition and customer setting. UPS, telecom DC power supply, TVSS and other equipments are connected to the central PDU. In the case of double power input loads, two UPS systems will feed with double power source. STS is needed for the single power input loads to one of the sources automatically. The modular UPS from Magnizon Power Systems is very suitable for the requirements of the modern large data center with high reliability.
