1440VA/940W/120V Battery Backup for PC Networks, Security Systems or Digital SignageThe OmniVS line-interactive OMNIVS1500XLCD UPS system with AVR protection provides reliable battery backup and AC power protection against blackouts, brownouts, overvoltages, surges and line noise that can damage valuable electronics or destroy data. The eight-outlet 120V battery backup is ideal protection for your home office, media center or commerce components, including computers, routers, printers, HDTVs, Blu-ray players, game consoles, ATMs, security systems and digital signage equipment.Allows Time to Back Up Critical Files During a BlackoutBackup support allows you to work through short power failures and gives you enough time to safely save files and shut down your system in case of a prolonged blackout. Backup time varies according to load, but the line-interactive UPS system should keep an energy-efficient desktop computer with small LCD monitor powered as long as 90 minutes (using internal batteries only).Supports an External Battery Pack for Extended RuntimeIn addition to the replaceable internal battery, the OMNIVS1500XLCD supports connection of one optional BP24V15RT2U external battery pack (sold separately). During normal operation, incoming utility power keeps the internal and external batteries fully charged, so backup power will always be available.8 NEMA 5-15R Outlets Protect Your Connected ComponentsSix 5-15R outlets provide battery backup, surge protection and voltage regulation for your computer, monitor and other crucial components. The other two 5-15R outlets provide surge suppression only for printers, speakers and other desktop equipment regarded as non-essential during a blackout.Automatic Voltage Regulation (AVR) Corrects Low- and High-Voltage ConditionsAVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts and overvoltages. The OMNIVS1500XLCD can correct brownouts as low as 89V and overvoltages as high as 145V back to nominal 120V power continuously, all while keeping the battery fully charged and ready to take over in case of power failure.Combats Line Noise That Can Harm EquipmentEMI (electromagnetic interference) and RFI (radio frequency interference) are common causes of performance problems and can lead to incremental hardware damage, data corruption and audio/video transmission problems. The OMNIVS1500XLCD filters out this disruptive line noise on the AC line, so that it won't affect your equipment.Designed for High Efficiency to Help You Save Money and Protect the EnvironmentA & gt; 95 percent efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.Home-Friendly Silent Alarm and LCD Touchscreen Keep You Informed 24/7The UPS remains silent in both line and battery backup modes. The alarm sounds only to report low battery, battery replace, overload and fault condition. The LCD touchscreen offers five screens of UPS and site power information when the UPS is operating in either on-line or battery power mode. It displays vital voltage, load and battery data, as well as critical fault status.Advanced Communications Ports Allow for Automatic Saves and ShutdownsRS-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. Cables are included.Compact Housing Compatible with Easy Desktop InstallationThe space-saving ABS tower fits on a desktop, shelf or any other flat surface convenient to your workstation or home theater. The five-foot power cord with NEMA 5-15P plug connects to any compatible AC outlet. A built-in fan regulates the internal temperature to help prevent overheating.
