The categories of
Modular UPS Power Supply are described as follows:
I. Definition and overview
Modular UPS power supply is a design architecture that divides the UPS system into multiple independent modules. Each module contains complete power conversion functions, such as inverters, rectifiers, batteries and control circuits, and can be operated independently, and modules can be added or reduced according to demand to adapt to different load requirements. This design improves the flexibility, reliability and maintainability of the UPS system.
Second, the main composition
Modular UPS power supply usually consists of the following main components:
Rack: The infrastructure that supports and holds each module.
UPS power module: Contains core power conversion components such as inverters, rectifiers, and chargers, which are responsible for converting input mains or battery power into stable AC power output.
Static switching module: Switches between mains and inverter output to ensure continuity of power supply.
Display communication module: Provides user interface and communication interface for monitoring UPS status and remote management.
Battery pack: Provides backup power to the UPS system to ensure continuous power supply in the event of a mains interruption.
Iii. Characteristics
Scalability:
Modular UPS allows the flexibility to expand or shrink system capacity based on load demand, by increasing or decreasing the number of modules.
Redundancy:
Each module has independent power and control functions, so the system is highly redundant. When one module fails, the other modules can continue to work, ensuring the continuous power supply of the load.
High reliability:
Due to the modular design, fault isolation is easier, and the failure of one module will not affect other modules, thus improving the reliability and availability of the entire system.
Simplify maintenance:
Modular design makes maintenance easier. When a module needs to be serviced or replaced, it can be done separately without the need to shut down the entire system, reducing maintenance time and interference with the load.
High performance:
Modular UPS systems typically have a high energy utilization rate, with the ability to adjust the number of modules according to load demand to provide greater efficiency. (
Intelligent management:
Many modular UPS are equipped with intelligent management systems, which can monitor the status of power supply, battery status, load, etc., and have fault diagnosis, automatic switching, remote monitoring and other functions.
