This 120V UPS system with AVR provides reliable battery backup and AC power protection against blackouts, brownouts, overvoltages, surges and line noise that can destroy data or damage valuable electronics. It is ideal for protecting home office, media center or commerce components, including computers, routers, printers, HDTVs, Blu-ray players, game consoles, ATMs, security systems and digital signage equipment . Battery backup allows you to work through short power failures and gives you time to save files and shut down your system in case of a prolonged blackout. Backup time varies according to load, but this line-interactive UPS system can keep an energy-efficient desktop computer with small LCD monitor powered as long as 88 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power is always available. Once utility power is restored after a prolonged outage, the UPS will automatically power up, even if the battery is expired and requires replacement. This battery independent restart feature eliminates the need to turn on the UPS manually after a blackout. Six battery/surge-protected outlets provide battery backup and surge suppression for your computer, monitor and other critical equipment. Two additional surge-protected outlets provide surge suppression for peripherals that do not require battery backup, such as printers and speakers. A high 95% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs. AVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts and overvoltages. The OMNIVS1200LCD corrects brownouts as low as 89V and overvoltages as high as 145V back to nominal 120V power continuously, all while keeping the battery fully charged. Rated to 316 joules, this UPS system protects equipment connected to the outlets and RJ45 jacks (1 in/1 out) from the harmful effects of power surges that can occur over AC and telephone/network lines. The RJ45 jacks are not compatible with Power over Ethernet (PoE) applications. EMI (electromagnetic interference) and RFI (radio frequency interference) are common causes of performance problems for electronics and can lead to incremental hardware damage, data corruption and audio/video transmission interruptions. The OMNIVS1200LCD filters out this disruptive line noise on the AC line to protect your equipment. 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. An audible alarm indicates low battery, excessive load or fault condition. The USB port connects the OMNIVS1200LCD to a computer running Tripp Lite's free downloadable PowerAlert software, enabling a graceful system shutdown during a prolonged power failure. USB cable is included. This HID-compliant UPS also works with the built-in power management features of Windows, Mac and Linux operating systems. The compact ABS housing fits easily on a desktop, shelf or anywhere else convenient to your workstation or home theater. The UPS has a 5-foot cord with a NEMA 5-15P plug for connection to a standard outlet.
