Centiel increases power density of its 4th generation modular UPS system: CumulusPower 


Centiel Ltd has launched new 25kW and 60kW UPS modules for its pioneering 4th Generation Modular UPS system, CumulusPower. This three-phase, modular system offers 99.9999999% (‘9 nines’) system availability with low total cost of ownership and now 20% more power density.  These new modules complete the family which also includes: 10kW, 20kW and 50kW options.

“Real estate is expensive and so data centres need to save space where they can,” says Mike Elms, sales and marketing director, Centiel Ltd.  “In addition, more space and racks in a facility can in turn, potentially generate revenue for the operation.  Therefore, a UPS which provides the most power, using the smallest footprint possible is a valuable asset.

“The new 25kW and 60kW versions of CumulusPower have all the benefits of our existing industry leading Modular UPS but now offer yet more power in the same the same footprint.  Unlike traditional multi-module systems, the CumulusPower technology combines a unique Intelligent Module Technology (IMT), with a fault-tolerant parallel Distributed Active Redundant Architecture (DARA), to remove single points of failure and offer industry leading availability.

“9 nines system availability is achieved through fully independent and self-isolating intelligent UPS modules – each with individual rectifiers, inverters, static bypass, CPU and communications logic and  display,” explains Mike.  “In the unlikely event of a module failure, the module can be quickly and safely ‘hot-swapped’ without transferring the load to bypass and raw mains.

“In addition, CumulusPower has been designed to reduce the total cost of ownership through low losses,” Mike confirms.  “The high double conversion efficiency of 97% at the module level means it is currently the best solution available to protect data centre infrastructure as its configuration also reduces downtime risk, avoiding costly errors as well as increasing energy efficiency.”
