The three major concerns of IT facility managers when assessing the life-cycle cost of their power protection infrastructure are availability, flexibility and total cost of ownership (TCO). The DPA UPScale ST is based on ABB’sunique and proven Decentralized Parallel Architecture (DPA) that has been developed specifically to respond to these concerns.
Parallel architecture limited only to modular design does not guarantee the highest power protection for critical applications. The success of a parallel modular system depends largely on the design of the parallel architecture and on the level of intelligence of the individual modules. Modular systems based on DPA are free of single points of failure and maximize the system’s mean time between failure (MTBF).Quick and simple repair by safe-swapping modules whilethe UPS is online minimize the system’s mean time to repair (MTTR).
UPS systems based on DPA allow for incremental expansions whilst ensuring redundancy at all times. It is possible to start with just a few modules and add to them as required in an easy and safe way. True safe-swap and safe-scale modularity enables the safe replacement of UPS modules and their integration into the UPS system without the need to transfer the critical load onto raw mains or to remove power from the critical load.
Saving costs and optimizing capital deployment are toppriorities, and IT facility managers must make effective investments to increase the efficiency of their IT systems. An infrastructure that uses cost-effective and flexible modular power protection solutions with significantly lower operating costs will create competitive advantages in the medium term.The DPA UPScale ST boasts the lowest cost of ownership of any UPS system by offering energy efficiency, scalable flexibility and highest availability due to true redundancy and easy serviceability.
