Modular UPS power supply modular UPS and conventional UPS difference
Traditional UPS requires professional and technical personnel to the site maintenance, modular UPS all modules are allowed to hot swap, the user can intervene in maintenance, directly replace the UPS spare module online.
Rackmounted modular UPS inherits the results of traditional UPS technology development in power device technology and manufacturing processes, but based on multi-module parallelism in system architecture, it not only enables hot-swapping of system modules, but also Processing the relationship between the independent operation of the system module, mutual cooperation and smooth conversion.
There are two types of rack-mounted modular UPSs.
One is the power modular UPS. Power modular rack-type UPS by the rack plus power module, the power module, including the traditional UPS rectifier, filter, charge, inverter and other parts. But the static bypass with the system part of the monitoring and display shared a rack. Each module independent control parallel operation, the upper part of the cabinet display control module only as a user switch UPS host and network monitoring platform.
The other is a fully modular UPS. This type of rack-mounted modular UPS is made up of rack-mounted modules. Each module is equipped with the entire UPS power supply and control circuit, including rectifiers, inverters, static bypass switches and ancillary control circuits, CPU main control board. Each UPS module has a separate management system.
On the relative level of power electronics and component development, the two types of structures have their own advantages, but also have a very good representative products, can provide the use of advanced decentralized parallel technology, so that the UPS system from centralized control technology Of the reliability constraints, to avoid the occurrence of bottlenecks, N + X parallel redundancy to provide a modular parallel system.
Power supply system to achieve on demand
Rackmounted modular UPS has a significant advantage over conventional UPS. Its advantages are mainly in the following three aspects:
Installation is simple, easy expansion, saving investment.
The rack-mounted modular UPS enables the power supply system to be on demand, allowing capacity to grow dynamically as the business grows. Both to meet the expansion of the latter part of the business needs, but also reduces the initial purchase cost of the user.
Parallel redundant, stable operation, high reliability.
In a rack-mount modular UPS, the power modules are partially redundant in parallel. Each module is equipped with input, output and input and output relays, and any module fails and does not affect the overall system operation.
In traditional UPS products, user security is generally used in the "1 +1" or "N + 1" parallel redundant mode, can only be fault-tolerant once. In the rack-mounted modular UPS system, users only need to purchase the corresponding power module, you can achieve "N + X" fault redundancy. "Modular redundant parallel structure" is more reliable than traditional UPS.
Easy maintenance, online disposal, high availability.
And the container in the factory began to load the same reason, the rack-mounted modular UPS installation and commissioning is also the beginning of the factory. In order to standardize the module-based UPS, in the product design, production, manufacturing process, you can develop a unified standard, so that all the components of the system can play the best performance, but also to avoid compatibility problems Of the system failure.
The rack-mount modular UPS can be configured according to current business requirements and can add more modules at a later time. The optimization capability of such a system significantly reduces the total cost of ownership.
Modular design provides great flexibility in reconfiguring power to meet changing business needs. Independent components, standard interfaces, and simple operations save time and save money when installing, upgrading, reconfiguring, or moving modular systems.
Rackmountable modular UPS can be installed in standard cabinets, saving floor space and space relative to traditional vertical (tower) structural UPS
In the installation, use and maintenance, can use a shorter power connection cable. By reducing the point of failure between the critical equipment and the load, the modular UPS can improve the overall system availability.
From the design and work of the principle, the modular UPS, including rectifiers, inverters, and some also include static bypass switch and ancillary control circuit, CPU main control board and so on. The biggest advantage of modularity is the ability to improve the reliability and availability of the system. Failure of any module does not affect the normal operation of other modules, but also reduces the installation and repair time of the system by hot-plugging.
In addition, the modular UPS can give users a better scalability, which also for the user's investment played a very good protection.
