Rack-mounted UPS and modular UPS are the two development directions of UPS technology. Since both rack-mounted UPS and modular UPS are lithium battery UPS placed on the rack, there are still big differences in the technological development direction of the two.

　　There are many differences between the two from the definition point of view. Next, the editor will briefly introduce the different definition points of rack UPS and modular UPS.

　　Rack-mounted UPS definition angle

　　The definition of rack-mounted UPS is from the perspective of external structure. Compared with the traditional tower structure, it can be installed together with the load in a standard cabinet.

　　Rack-mounted UPS is a lithium battery UPS designed to meet the growing needs of communication networks. The rack-mounted installation method makes it more advantageous than traditional tower UPS power supplies in terms of space occupation, connection and wiring, and visual unity. It can meet the user's requirements for integrated installation.

　　Modular UPS definition angle

　　Modular UPS is based on the design and working principle. The module itself is a UPS. It not only includes the rectification, filtering, charging, inverter and other devices of traditional UPS, but also has intelligent power protection functions.

　　The different advantages of the two in application

　　location placement

　　The main application fields of rack-mounted UPS and modular UPS are in data center computer rooms. Due to its integrated design, rack-mounted UPS can be placed on the same rack as the load in the computer room.

　　Modular UPS has its own equipment such as rectifier, inverter, static bypass and CPU main control board all placed in a cabinet. The UPS itself should be placed in different cabinets separately from the load.

　　Maintenance management

　　Rack-mounted UPS is usually placed together with the load, which can effectively save the floor space and space of the UPS, and can also be more convenient during installation, use and maintenance.

　　The centralized and unified management of rack-mounted UPS and loads makes it easier to leverage the intelligent management functions of UPS. Nowadays, as management requirements are getting higher and maintenance costs are becoming more and more important, the advantages and value of rack-mounted UPS in centralized management are becoming more and more obvious.

　　The biggest advantage of modular UPS is that it can improve the reliability and availability of the system. When one module fails, it will not affect the normal operation of other modules. Its hot-swappable feature can also greatly shorten system installation and repair time.

　　Although rack-mounted UPS and modular UPS are two different development directions in UPS technology and have many differences, in terms of scalability, both can effectively save their expansion costs.

　　Because the rack-mounted UPS is an integrated design, it is placed together with the load. When the load increases, you only need to add a rack-mounted UPS simultaneously, which is very convenient.

　　Some modular UPS have no limit on the number of modules and can be used in parallel. Modules of the same or different power can also be combined at will, which will also help users expand the UPS in the future.
