What are the advantages and disadvantages of modular UPS battery? In what areas? Modular UPS power supply is composed of rack, UPS power module, static switch module, display communication module and battery pack. It is generally used in Internet data center, computer room and communication system.

■ advantages of modular UPS power battery:

1. The system structure of modular UPS battery is very flexible. The design concept of power module is that it can be removed and installed at will during the operation of the system without affecting the operation and output of the system, so as to realize the "on-demand expansion" of investment planning and the "dynamic growth" of users with business development, which not only meets the on-demand expansion of later equipment, but also reduces the initial purchase cost.

2. N + X redundancy technology is adopted, with reliable performance. It is a redundant and scalable system, which can be upgraded according to customer needs. The risk coefficient of the system itself and the load is reduced, so that the load is protected by modular UPS, and the time is comprehensively improved.

3. Green power supply, high efficiency and energy saving, input power factor PF ≥ 0.99, and its inverter efficiency can reach more than 98%, which improves the working efficiency of the whole machine, reduces loss and saves electric energy.

4. Intelligent power distribution system, modular UPS power supply input and output integrated power distribution system, which is used together with UPS host. Lithium ion battery is installed in battery cabinet with the same brand, appearance and color as UPS host.

5. Modular UPS has high working efficiency and high power density. The model is composed of various modules, which can realize the hot plug-in function, and the racks of each module can be completely separated, which is convenient for users to expand or reduce capacity in the future.

6. The modular UPS battery is easy to install, maintain, replace and upgrade, which reduces the maintenance difficulty and time, and the size of each module is designed according to the standard 19 inch structure, reducing the initial purchase cost of users.

7. The tower type / rack type can be selected flexibly, which can be configured flexibly according to the needs of users, and the lithium-ion battery pack can be shared in parallel, so as to reduce the floor area and save the investment cost of the battery system.

■ disadvantages of UPS battery Modularization:

1. The difficulties in the development of modular UPS power supply mainly focus on the improvement of power density, the addition of parallel quantity and the reduction of price. The budget cost under the same power load capacity will be much higher than that of traditional UPS, and the product cost will increase.

2. The more modular UPS, the more fault points, and the lower system reliability.

3. Due to the limitation of volume, when the power of UPS module increases, heat dissipation becomes a big problem.

Summary: with the rapid development of Internet, cloud computing, mobile Internet, Internet of things and other technologies, the scale of data center system is increasing and its importance is becoming higher and higher. Ups will undoubtedly meet this requirement. Modular UPS power supply has so many advantages. Modular ups will cause a new revolution of uninterruptible power supply and become the development trend of UPS system in the future. This article makes a comprehensive analysis of the advantages and disadvantages of modular UPS, hoping to give readers some help and inspiration.
