Modular UPS technology is considered the trend of development. When compared to the traditional sense of the UPS, modular UPS has three main advantages.

First, the "modular redundant parallel" technology can avoid waste of resources. The user's information network in the industry supply system construction, often high-end UPS capacity will generate an error, or is too low or too high than what expected, the results could lead to high procurement cost, or cannot meet the load needs or cause resources, space and energy waste and so on. Modular, scalable UPS module structure through an effective solution to this problem, it can help users in the future development where the construction phases and investment can be done.

Second, high security and easy to maintain hot-swap technological can make breakthrough in application bottlenecks. Traditional high-end UPS during routine maintenance, equipment maintenance all need to be taken during the switch to bypass mode, while the load in this case is not subject to UPS protected. Therefore, if this time a power interruption happened and overload such as malfunction, it would cause serious losses, and its maintenance process is relatively cumbersome and not conducive to aging. Modular UPS systems that can be used in hot-swap technology allows single modules without any power failure to enter or exit the premise of parallel units, thus achieving an online parallel system maintenance, while no special equipment or techniques can be carried out.
