In recent years, with the rapid development of big data, cloud computing and other technologies, the traditional data center system is also changing rapidly. As a key component of the data center power supply and distribution system, the UPS industry is also changing. Modular UPS technology is becoming more and more mature, and more and more users have or are considering using modular UPS to build new data centers. Large-capacity modular UPS, the status of traditional tower UPS is being challenged.

In the face of the overwhelming publicity of many UPS manufacturers, as well as the different viewpoints of various technical schools. How to choose a suitable modular UPS and what kind of UPS is a real modular UPS is perplexing many UPS users. This article will answer this dilemma for the reader.

Why to use a modular UPS?

In fact, many users ask this question. The common understanding in the industry is that in terms of installation, maintenance and later capacity expansion, modular UPS has the irreplaceable advantages of tower UPS. In terms of green environmental protection, high efficiency and energy saving, it mainly depends on the internal circuit of the UPS and the technology used, such as IGBT rectification or SCR rectification, whether the output has an isolation transformer, etc., which has little to do with the external structure. However, it should be noted that compared with the early power frequency machines, most of the current modular UPSs have obvious advantages in reducing harmonics and improving efficiency because of the use of high-frequency technologies such as transformer less design and IGBT rectification. The technical highlights of high-frequency tower UPS compared to traditional power-frequency UPS.
