It conditions, regulates, and filters out power disturbances to ensure a clean power source for ITequipment. A UPS also provides battery backup if there is a power failure.In today’s high availability server environments, unplanned power outages or line quality irregularities canhave a considerable financial impact on all sized businesses. The typical utility power is 99.9% available,but that means that there can be almost 9 hours of downtime a year, not to mention brownouts and otherpower quality problems. Selecting the right UPS can help protect against these potentially costly issues.The RT8kVA and RT11kVA 6U Rack or Tower UPS units protect against the following power problems:power failures, power sags, power surges, under-voltage, electrical line noise, over-voltage, frequencyvariation, switching transients, and harmonic distortion.The RT8kVA and RT11kVA 6U Rack or Tower UPS models offer the following features:High-efficiency protection delivers more real power (Watts) in a compact tower or 6U rack design,which lowers power and cooling consumptionGraphical Liquid Crystal Display (LCD) provides intuitive configuration, management, and monitoringcapabilities in the following languages to reduce management complexity:EnglishFrenchGermanSpanishRussianPortugueseItalianHot-swappable batteries for maximum uptime, availability, and ease of maintenanceStandard UPS Power Manager software provides effective local or remote power monitoring andmanagement for servers and virtual machines, and allows for graceful remote system shutdownABM technology significantly extends battery service life and optimizes recharge timeOptional external battery modules (EBMs) provide extra run time to critical systems during aprolonged power outageStandard NMC provides enhanced UPS monitoring and control over-the-network through astandard web browserOptional Environmental Monitoring Probe provides thermal management requirements (temperatureand humidity)Standard Maintenance Bypass enhances availability by providing service continuity during UPSRT8kVA and RT11kVA 6U Rack or Tower Uninterruptible Power Supplies 4
