The Tripp Lite SMART1500SLT SmartPro 120 V 1.5 kVA 900 W line-interactive sine wave UPS 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 VoIP systems, point-of-sale applications and network closets, the SMART1500SLT switches to battery mode in milliseconds to keep your connected equipment running long enough to save files and shut down safely with no data loss. Featuring eight (8) NEMA 5-15R outlets and a 6 ft power cord with NEMA 5-15P input, the SMART1500SLT has an internal battery that provides 20 min of support at half load and 8 min at full load. Front-panel LEDs indicate line power, battery power, overload, voltage regulation and battery status. An alarm sounds to indicate power failure and overload conditions. Automatic voltage regulation (AVR) maintains selectable 100 V, 110 V or 120 V nominal output over an input range of 95 V – 145 V without using battery power. EMI/RFI noise filtering improves your equipment’s performance and prevents damage. A 690 J surge suppression rating protects your equipment from harmful power surges. With Tripp Lite’s included PowerAlert software, the SMART1500SLT enables safe unattended system shutdown and file saves in case of a prolonged power failure. Adding an optional Tripp Lite SNMPWEBCARD accessory card permits remote management of the UPS, including reboots and activity logs.
