Modular UPS flexible & redundant power protection

The modular concept enables you to flexibly adapt the UPS power to your personal power needs. The individual modules are hot-swappable, connected modules are automatically detected. You can upgrade your system within just a few minutes while the system is running. The automated load distribution among all modules within a system enables a modular n+x redundancy that can also be used for load increase.

Advantages:

Precise scalability - higher efficiency

Modular UPS architectures offer the major advantage of much smaller design dimensions – enabling performance to be adjusted to the actual load much more precisely. Additional capacity modules are only added when the load increases, ensuring that the system always operates at optimum efficiency.

Depending on the size of the cabinet, the system capacity can be expanded, to ten times the original installed capacity, for example. If the system capacity still does not satisfy the increased demands, further systems can be added – making this architecture the most flexible solution for applications ranging from small server rooms to large-scale data centres.

Maintenance

Modular UPS systems also boast easier maintenance, as only one module at a time is removed for maintenance and then reinstalled once complete; a process that is significantly simpler than with traditional UPS architectures, which require the entire UPS to be disconnected from the consumers. The advantage of this approach is that all consumers continue to be protected by the UPS during the maintenance work, and the time spent connected to the mains network is reduced to a minimum, for the performance of a short system functionality test.

Higher availability

In high-availability date centres certified in line with EN 50600-2-2 for "high" overall availability (availability class 3), which are required to guarantee an availability of 99.995%, other reliability aspects must be taken into consideration: UPS systems themselves are not immune to technical failures, and must be redundant in design. In classic UPS architecture, two redundant systems must be installed so that the second system can replace the first in the event of a failure. As a result, each of the systems can be operated at a maximum of just 50% load. For EN 50600-2-2 "very high" classifications (availability class 4), the system is no longer operated at 50% load, but instead at a lower rate, depending on the module size. For this reason, special attention should be paid to suitable module sizes and high partial load efficiency when selecting components for the system.

In modular architectures, it is not necessary to build redundancy into the entire UPS – it is sufficient for one or two modules to be designated as redundant and compensate for the failure of another module. In the event of a failure, the system automatically switches to a functional module and immediately reports the failure to a technician, who can then replace the module while the system is operational. In very advanced systems, modules can even respond autonomously to the failure of another module, enabling the system to independently eliminate sources of faults within the system cabinet.
   

Global Monitoring & quicker restoration

A key element of any maintenance concept is the continuous monitoring of the UPS. Continuous monitoring allows the maintenance team to act quickly and restore system reliability if individual modules fail. In the best-case scenario, the user is able to rapidly get the system back up and running by replacing the faulty module, or with telephone support from the manufacturer – avoiding the additional costs that are associated with customer service interventions.

Monitoring becomes particularly complex when an IT department manages multiple locations. If the operator needs to maintain a clear overview of systems made by different manufacturers, the challenge is even greater. In such cases, cloud solutions, such as MoniUPS from AEG Power Solutions, are invaluable. As the software is hosted in the cloud, there are no installation and maintenance costs. A single interface for all of the shared UPS systems makes configuration significantly easier and reduces the amount of employee training required.
