DARA - Take your power availability to the next level

When it comes to availability, it’s what’s inside that counts

It is essential to have a UPS system that you can rely on to keep your critical infrastructure up and running 24/7. That’s where DARA comes in. DARA stands for Distributed Active Redundant Architecture, and it’s the technology that powers StratusPower. With DARA, you can be confident that your data center will have the highest level of protection against power outages and other electrical disruptions.

In DARA, all modules collaborate to make critical decisions to secure your load remains energized. This process involves teamwork among the modules, with multiple controllers ensuring redundancy and efficiency in delivering maximum energy security in the event of a power failure. This approach enables the UPS to make informed decisions that optimize power supply, minimize downtime and safeguard critical loads.

  • Mean time to repair (MTTR)

    DARA’s technology on the frame level has been designed to accommodate non-intrusive maintenance and to minimize mean time to repair (MTTR), ensuring that any downtime is kept to an absolute minimum. For example, in the event of a power failure, fuses and switches can be quickly accessed without removing modules.
