The Tripp Lite SmartPro SMART1300LCDT LCD Line-Interactive UPS Tower provides battery backup and AC power protection against blackouts, brownouts, power surges and line noise that can damage electronics or destroy data. Ideal for backing up your desktop computer or audio/visual components, this line-interactive UPS switches to battery backup mode in milliseconds to keep your connected equipment running long enough to save files and shut down safely with no data loss. While all 8 NEMA 5-15R outlets protect against surges, 4 outlets also provide up to 64 minutes of UPS battery support for a basic desktop PC and LCD monitor and up to 10 minutes of support at half load (360 watts). AVR corrects undervoltages as low as 92 volts and overvoltages as high as 150-volts without using any battery power. EMI/RFI noise filtering improves your equipment?s performance and prevents damage. A 650-joule surge suppression rating protects your equipment from harmful power surges. A NEMA 5-15P plug with 6 ft. cord connects to any NEMA 5-15R socket. The large LCD screen shows real-time input voltage, overload, AVR, remaining battery runtime and battery statuses at a glance. An alarm sounds to indicate power loss or low battery. With Tripp Lite?s free PowerAlert software (available via free web download), the SMART1300LCDT enables safe unattended system shutdown and file saves in case of a prolonged power failure.
