Designed specifically for high-density computing environments, the Powerware® BladeUPS delivers 12KW of efficient, reliable power in only 6U of standard rack space, including batteries. Expand capacity by combining 12 KW modules in a building block fashion to deliver 60 KW of redundant backup power from a single rack enclosure. This powerful configuration delivers higher power density than competitive, modular solutions, while dissipating one-third of the heat. The standard internal batteries provide needed ride-through power until an auxilliary power source takes over or systems are gracefully shut down. Extend runtime up to 34 minutes at full load (or 73 minutes at half load) with Extended Battery Modules (EBMs).
