Modularization is considered to be the trend of UPS technology development. Compared with UPS in the traditional sense, modular UPS has three major advantages.

First, the "modular redundant parallel connection" technology avoids waste of resources. In the construction of the information network power supply system of industry users, the capacity of high-end UPS is often incorrectly estimated, either too low or too high. As a result, it may lead to excessive procurement costs, inability to meet load needs, or resources , Space and energy waste. Modular UPS effectively solves this problem through an expandable modular structure. It can help users build and invest in stages when the future development is not clear.

Second, the high-safety, easy-to-maintain hot swap technology has broken through the application bottleneck. Traditional high-end UPS needs to be switched to bypass during routine maintenance and equipment maintenance, and the load is not protected by UPS in this case. Therefore, if power interruption, overload and other faults occur at this time, serious losses will be caused, and the maintenance process is relatively cumbersome and unfavorable for aging. The hot-swappable technology used in the modular UPS system can allow individual modules to enter or exit the parallel unit at will without power failure, thereby realizing the online maintenance of the parallel system without special equipment or technology.

Third, the power phase multi-system technology reduces procurement and management costs. The power input and output phases of traditional high-end UPS are fixed, so when users construct power supply systems, they often increase the number of UPSs for different phases and capacities. In the modular UPS system, the power phase multi-system technology can be used to change the constraints caused by the unity in the past, and users no longer need to consider how to purchase UPS products of different phases or capacities to meet the needs of the system.

Compared with the traditional vertical (tower) structure UPS, the rack-mounted modular UPS can be installed in a standard cabinet, saving floor space and space

In terms of design and working principles, modular UPS includes rectifiers, inverters, and some also include static bypass switches, auxiliary control circuits, and CPU main control boards. The biggest advantage of modularization is that it can improve the reliability and availability of the system. The failure of any module will not affect the normal operation of other modules, and the hot-swappable feature can shorten the installation and repair time of the system.

In addition, modular UPS can bring better scalability to users, which also plays a very good role in protecting users' investment.

Just as the container starts loading at the factory, the installation and commissioning of the rack-mounted modular UPS also starts at the factory. The UPS based on standardized modules can formulate unified standards in the product design, production, and manufacturing process, so that all components in the entire system can exert the best performance, while avoiding compatibility problems. System failure.

Rack-mounted modular UPS can be configured according to current business needs, and more modules can be added in the future. The optimization capability of this system significantly reduces the total cost of ownership.

The modular design provides great flexibility in reconfiguring power to meet changing business needs. When installing, upgrading, reconfiguring or moving a modular system, independent components, standard interfaces, and simple operation save time and money.

Power supply system realizes on demand

Rack-mounted modular UPS has considerable advantages compared with traditional UPS. Its advantages mainly include the following three aspects:

The installation is simple, the expansion is convenient, and the investment is saved.

Rack-mounted modular UPS enables the power supply system to respond on demand, allowing the capacity to achieve "dynamic growth" as the business develops. This not only satisfies the needs of later business expansion, but also reduces the initial purchase cost of users.

Parallel redundancy, stable operation and high reliability.

In the rack-mounted modular UPS, the power modules are redundant in parallel, and each module is equipped with input and output fuse and input and output relays. Any failure of any module will not affect the operation of the entire system.

In traditional UPS products, users generally adopt the "1+1" or "N+1" parallel redundancy mode to ensure safety, which can only tolerate faults once. In the rack-mounted modular UPS system, users only need to purchase the corresponding power modules to achieve "N+X" failure redundancy. "Modular redundant parallel structure" is more reliable than traditional UPS.

Easy maintenance, online disposal, high availability.

Traditional UPS requires professional and technical personnel to repair on site. All modules of modular UPS are allowed to be hot-swappable. Users can intervene in maintenance and directly replace UPS spare modules online.

Rack-mounted modular UPS inherits the achievements of traditional UPS technology development in terms of power device technology and manufacturing process, but in terms of system architecture, based on multi-module parallel connection, it not only realizes the hot swap of system modules, but also better The relationship of independent operation, mutual cooperation and smooth conversion of system modules is handled.

Rack-mounted modular UPS has two representative structures.

One is the power modular UPS. The power modular rack UPS consists of a rack plus a power module. The power module includes the rectification, filtering, charging, inverter and other parts of the traditional UPS. But the static bypass shares the same rack with part of the system's monitoring and display. Each module is independently controlled and operated in parallel, and the display control module on the upper part of the cabinet is only used as a user switch UPS host and a networked monitoring platform.

The other is a fully modular UPS. This type of rack-mounted modular UPS is composed of racks and single modules. Each single module is equipped with the entire UPS power supply and control circuit, including rectifier, inverter, static bypass switch and auxiliary control circuit, CPU main control board. Each UPS module has an independent management system.

In terms of relative power electronic technology and component development level, the two types of structures have their own advantages, and both have excellent representative products. Both can provide advanced decentralized parallel technology, so that the UPS system is not subject to centralized control technology. The reliability is limited, avoid bottleneck failure, and provide modular parallel system with N+X parallel redundancy function.
