The Tripp Lite SMART1500RMXL2UA SmartPro 120 V 1.5 kVA 1.35 kW 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 servers and network storage devices, the SMART1500RMXL2UA 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 (four switchable) and a 10 ft power cord with 120 V NEMA 5-15P input, the SMART1500RMXL2UA has an internal battery that provides 14 min of support at half load and 4.9 min at full load. A front-panel LCD screen lets you monitor important data, such as load level, voltage, battery charge, and estimated runtimes. Adding external battery packs, such as Tripp Lite’s BP36V15-2U (sold separately), provides extended runtime. Automatic voltage regulation (AVR) maintains 120 V nominal output over an input range of 83 V – 145 V without using battery power. EMI/RFI noise filtering improves your equipment’s performance and prevents damage. A 570 J surge suppression rating protects your equipment from harmful power surges. With Tripp Lite’s included PowerAlert(R) software, the SMART1500RMXL2UA 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.
