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.

The versatile
Universal Rack UPS solution

Available as a Universal Rack UPS, StratusPower offers a blend of technical and commercial benefits tailored to meet a variety of power protection needs. This adaptable system includes the UPS, communication components, battery breakers and output switches, making it ideal for integrated IT, telecom or other critical processes. The UPS integrates seamlessly into any 19-inch rack, regardless of the rack manufacturer.

With its versatile design, StratusPower simplifies the engineering and deployment of custom power protection solutions. System integrators can leverage their expertise and implement unique solutions to meet specific design requirements. The UPS can be seamlessly integrated into weatherproof enclosures, making it ideal for applications in harsh environments.

The Universal Rack Solution provides efficient heat management by directing warm air to the rear of the cabinet for optimal cooling without affecting the entire enclosure.

For system integrators, the Universal Rack solution offers efficient customisation with standard products and the opportunity to add significant local value to their power protection solutions.

The Universal Rack offers versatile battery placement options, allowing either top or bottom customisation to suit specific preferences and operational requirements.

Thanks to the minimal size of the 10/20/25 and 30kW modules, the Universal Rack UPS solution is available in compact depths from 600 mm, providing a space- saving solution without compromising performance.
