Compact Desktop 650VA/330W Battery Backup for PCs, Home Theater and Digital Signage This 120V UPS system 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 professional kiosk, security and small-business phone applications, 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 Blackout Backup 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 INTERNET650U1 should keep an energy-efficient desktop computer with small LCD monitor powered as long as 17 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available. HID-Compliant USB Port Allows for Automatic Saves and Shutdowns This port connects the INTERNET650U1 to a computer running Tripp Lites free downloadable PowerAlert software to enable safe unattended file saves and system shutdown in case of a prolonged power failure. USB cable is included. The UPS works with Windows, Mac and Linux operating systems. Connects Your Equipment to 8 Protected NEMA 5-15R Outlets Four 5-15R outlets provide both battery backup and surge protection to your computer, monitor and other crucial components. The other four are surge-protected only for printers, scanners and other non-essential equipment. A 316-joule surge suppression rating protects connected components from the harmful effects of power surges. Two outlets are spaced apart from the others to accommodate bulky transformers. RJ45 jacks protect a standard dial-up/DSL phone connection or 10Base-T Ethernet line connection from data line surges. Charges Mobile Devices, Including Smartphones and Tablets A USB charging port delivers up to 5V 1A maximum charge current for keeping your phone, MP3 player and other USB-compatible device at 100% capacity. Combats Electromagnetic Interference That Can Harm Equipment Various electromagnetic and radio sources found in virtually every home and business can cause disruptive interference on the AC line. Known as EMI (electromagnetic interference) and RFI (radio frequency interference), this line noise is a common cause of performance problems and can lead to incremental hardware damage, data corruption and audio/video transmission problems. The INTERNET650U1 incorporates technology that filters out disruptive line noise so that it won't affect your equipment. Diagnostic LED and Audible Alarm Keep You Informed Front-panel green LED indicates line/battery mode status, overloads and low/replace battery alert. A home-friendly alarm stays silent in AC and battery modes, except to warn you of a low battery or fault condition. High Line-Mode Efficiency Saves Energy and Cuts Costs A high & gt;98% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs. Compact Housing for Convenient Installation Almost Anywhere The space-saving housing fits easily on a desktop, shelf or anywhere else convenient to your workstation. Keyhole mounting tabs allows easy wall installation. The five-foot power cord with NEMA 5-15P plug connects to a standard AC outlet.
