The IBM® 11000VA LCD 5U Rack uninterruptible power supply (UPS) optimizes for both efficiency and performance, providing the right level of power protection for the moment. This online double-conversion UPS delivers 10,000 watts of clean conditioned power with an efficiency rating of up to 96% to protect your IBM System x®, PureSystems and BladeCenter® investment, improve availability, and reduce energy consumption. The power-dense 5U design conserves rack space, allowing for the protection of more equipment and leaving room for future IT expansion. Unlike other competing UPS topologies, the IBM 11000VA UPS features online double-conversion technology to fully protect connected equipment from all nine of the most common power problems: outages, sags, surges, spikes, brownouts, line noise, frequency variation, switching transients, and harmonic distortion. The UPS has a bright, easily customizable, graphical LCD display that lets you configure the device and displays important UPS status information in one of nine languages. This UPS enhances system availability with Advanced Battery Management (ABM) technology, which significantly extends battery service life and optimizes recharge time, and by providing individual control of receptacle groups that can maximize run time for critical devices in the event of a prolonged power outage. It also provides a real-time clock that enables precise shutdown and powerup of systems in a preferred sequence, and records specific power-related occurrences for more accurate trending and data analyses. The IBM 11000VA UPS integrates with IBM Systems Director Active Energy Manager™ to help improve energy management.
