Uninterruptible power supply – 2011-03-03

APC announced new parallel capabilities of the Symmetra PX 250/500kW three-phase modular and hot scalable uninterruptible power supply (UPS). This new firmware ships standard on all Symmetra PX250/500kW units, which can now be paralleled to deliver up to 2 MW of power protection or 1.5 MW in a system level redundancy (N+1) configuration. The Symmetra PX250/500 kW provides scalability and availability up to 2000 kW. The Symmetra PX250/500 kW offers a modular, hot-scalable system consisting of redundant modules: power, intelligence, battery, and communications. Each system is scalable in 25 kW increments up to 500 kW with the ability to run up to four systems in parallel to provide 2 MW of redundant power protection. The architecture reportedly gives IT managers the ability to right-size power and runtime as demand grows or as higher levels of availability dictate.
