    Manufacturer Website Address
    Marketing Information350VA/210W/120V Battery Backup for PCs, Home Theater and Digital Signage
    The standby INTERNET350U 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 six-outlet 120V battery backup is ideal protection for your home office, media center or commerce components, including computers, routers, printers, NAS drives, HDTVs, Blu-ray players, game consoles, media players, DVRs and audio receivers.
    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 INTERNET350U should keep an energy-efficient desktop computer with small LCD monitor powered as long as 13 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available.
    6 NEMA 5-15R Outlets Protect Your Connected Components
    Three 5-15R outlets provide battery backup and surge protection for your computer, monitor and other crucial components. The other three 5-15R outlets provide surge suppression only for printers, speakers and other desktop equipment regarded as non-essential during a blackout. Each outlet offers wide spacing to accommodate bulky transformer plugs. A high >98% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.
    316 Joules Fight Back Against Unexpected Power Surges
    A 316-joule surge suppression rating protects connected components from the harmful effects of power surges. Dual network data line surge suppression jacks protect a wired peripheral from dangerous surges on a single 10/100Base-T or dial-up network connection.
    HID-Compliant USB Port Allows for Automatic Saves and Shutdowns
    This USB port connects the INTERNET350U to a computer running free downloadable PowerAlert® software to enable safe unattended file saves and system shutdown in case of a prolonged power failure. USB cable is included.
    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 INTERNET350U incorporates technology that filters out disruptive line noise so that it won't affect your equipment.
    Home-Friendly Alarm and Diagnostic LEDs Keep You Informed 24/7
    The UPS remains silent in both line and battery backup modes. The alarm sounds only to warn you of a low battery or fault condition. A front-panel green LED indicates operating mode and fault status.
