The Difference between Rack-mount UPS and Modular UPS

2018-11-23

Rack-mount UPS are primarily capable of being installedin standard cabinets compared to conventional tower UPS. Its production comes from the requirements of the overall space layout of the machine room. The server and network equipment are installed in a standard cabinet in a rack structure. If the UPS is a conventional tower structure, it requires a separate storage space, which is neither aesthetically pleasing nor economical. If it is made into a rack-mount structure, it is placed in the remaining space in the cabinet and integrated with the load equipment to achieve a simple machine room layout, improve space utilization, and facilitate centralized monitoring and management.


Modular UPS with full UPS power and control circuitry in each module, Including rectifiers, inverters, static bypass switches and associated control circuits,CPU main control board. Each UPS module has an independent management system. Compared to conventional tower UPS, Its greatest advantage is its ability to increase system reliability and availability. Because the failure of one module does not affect the normal operation of other modules, and the hot-swappable feature can greatly shorten the installation and repair time of the system. In addition, the modular UPS can provide users with better scalability, which also provides a good protection for the user's investment.


The common advantage of rack-mount and modular UPS power is space saving and easy management. The difference is that rack-mounted UPS tends to concentrate on small and medium capacity, while modular UPS can achieve very large capacity by paralleling.
