550VA/300W/120V Battery Backup for PCs, Home Theater or Digital Signage
This SmartPro® line-interactive 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 SMART550USB is ideal protection for your home office, media center or commerce components, including gaming PCs, routers, printers, HDTVs, Blu-ray players, game consoles, ATMs, security systems, small business phone systems and digital signage equipment.

Reliable, Expandable Battery Backup Keeps You Operational Through Power Outages
The field-replaceable, hot-swappable battery module allows you to work through short power failures and give you enough time to safely save files and shut down your system in case of a prolonged blackout. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available.

Connects Your Equipment to 6 NEMA 5-15R Outlets
Three 5-15R outlets provide both battery backup and surge protection for your computer, monitor and other crucial components. The other three 5-15R outlets are surge-protected only for printers, scanners and other non-essential equipment.

Automatic Voltage Regulation (AVR) Corrects Low- and High-Voltage Conditions
AVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts and overvoltages. The SMART550USB can correct brownouts as low as 89V and overvoltages as high as 139V back to nominal 120V power without drawing on the battery backup needed to support your equipment during a blackout.

Premium Protection from EMI/RFI Line Noise Helps Your Equipment Perform Better
This UPS system filters out disruptive electromagnetic and radio frequency interference that can inflict hardware damage or data loss. This EMI/RFI filtering also helps your connected components perform better and last longer.

Easy-to-See LEDs Report Real Time UPS and Power Status
Front-panel LEDs provide UPS and site power information when the SMART550USB is operating in either on-line or battery power mode. They indicate operating mode, low battery, overload and fault condition. An audible alarm will sound in case of low battery, excessive load and fault condition.

HID-Compliant USB Port Allows for Automatic Shutdowns
This port connects the SMART550USB to a computer running free downloadable PowerAlert® software to enable safe unattended system shutdown in case of a prolonged power failure. USB cable is included.

Includes Power Protection for your Phone and Network Lines
Dual RJ11 jacks protect your modem, fax machine or other equipment against surges over a single telephone or network line.

Tower Form Factor for Easy Placement in Your Workspace or Media Center
The long-lasting plastic housing fits easily on a desktop, shelf or anywhere else convenient to your workstation or home theater. The six-foot (1.8-meter) power cord with right-angle NEMA 5-15P plug connects to a properly grounded AC wall outlet.
