CENTIEL’s CumulusPower is a three-phase UPS which offers continuous power availability, fault-tolerance, and ‘Distributed Active Redundant Architecture’ (DARA). The latter removes single points of failure, according to the manufacturer.
The unit from the Swiss vendor is exclusively available in the UK from MPower UPS. Unlike traditional multi-module systems, it claims CumulusPower combines DARA with unique ‘Intelligent Module Technology’ to offer 99.9999999 per cent availability. The company explains that this is achieved through fully independent and self-isolating intelligent modules, with individual power units, intelligence (CPU and communication logic), static bypass, control display and battery. In the “unlikely” event of a failure, modules can simply be swapped without transferring the load to raw mains, says MPower.
The UPS has been designed to reduce total cost of ownership through low losses with high double conversion efficiency of what the company says is 97 per cent at the module level. It adds that the small footprint contributes to achieving a high power density of 412kW/m2 with an input THD of less than three per cent.
Furthermore, vertical and horizontal scalability means clients can pay as they grow as CumulusPower modules can be connected in parallel configurations to provide redundancy or to increase a system’s total capacity.
MPower says serviceability is also straightforward with simple fault clearance and tool-less replaceable, hot-swappable modules.
