Double-Conversion UPS Protects Equipment against Damage, Downtime and Data Loss This 200/208/220/230/240V 50/60 Hz UPS system maintains perfect output by converting AC input to DC, then reconverting UPS output to fully regulated sine wave AC with +/-2% voltage regulation in online and battery modes. Featuring a 900W capacity, high 0.9 power factor, 627 joules of surge suppression, true on-line operation with pure sine wave output and zero transfer time to battery mode in on-line double-conversion mode, the SmartOnline® SUINT1000LCD2UN double-conversion UPS provides the highest level of AC power protection and battery backup for critical network closet, computer room and data center equipment. Set Power Strategies to Reflect Your Protection Priorities Pick your power strategy, from precise power for sensitive systems to the highest possible electrical efficiency, while ensuring 100% uptime. Choose from five selectable strategies: Max Efficiency, Max Quality, Frequency Regulation, Frequency Conversion and Auto Adaptive, which automatically offers increased efficiency when power conditions are good and enhanced power quality when power conditions are poor. Individually Controllable Load Banks Let You Access and Control Outlets Remotely Four C13 outlets are split evenly into two switchable load banks, allowing you to reboot select components or shed loads remotely. In addition to those four outlets, this UPS provides two more C13 outlets in their own unswitched bank for powering critical components. Reliable, Expandable Battery Backup Keeps You Operational Through Power Outages The field-replaceable, hot-swappable internal battery (RBC24S) provides 12.3 minutes of support at half load (450W) and 4.7 minutes at full load (900W), keeping protected equipment operational through power failures. For mission-critical applications demanding scalable extended runtime, the UPS supports "smart" external battery packs, such as Tripp Lite's BP24V36-2US (sold separately). Both the internal and external batteries are automatically sensed and configured during replacement to offer accurate runtime-remaining and battery age notifications during outages. The intelligent battery management system with temperature-compensated charging extends battery life. Automatic Bypass Maintains Utility Output During Fault Conditions Auto-bypass mode keeps connected equipment powered and operational, even during UPS fault conditions. ENERGY STAR-Certified Economy Mode Helps You Save Money and Protect the Environment By meeting strict EPA efficiency guidelines, this ENERGY STAR-certified UPS system helps you save money and energy. A power-saving Economy mode setting option offers enhanced efficiency and reduced BTU output when utility power is already high quality. Automatically Turns Back On After Power Is Restored Battery-independent restart ensures automatic UPS power-up without user interaction after lengthy power outages, even when batteries are expired and require replacement. Intuitive Front-Panel Interface for Convenient UPS Operation and Monitoring The front-panel LCD screen reports UPS operating mode, detailed UPS status and site-power information, as well as a variety of advanced UPS setup and configuration options. LEDs indicate AC input/output, battery and fault status. Advanced Communications Ports Allow for Automatic Saves and Shutdowns RS-232 and HID-compliant USB ports connect to a computer running Tripp Lite's free downloadable PowerAlert® software to enable safe unattended file saves and system shutdown in case of a prolonged power failure.
