The SMART1500CRMXL SmartPro 120V 1.5kVA 1.44kW 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 SMART1500CRMXL switches to 1.5kVA/1.44kW 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 NEMA 5-15R outlets (three switchable) and a 10-foot power cord with 120V NEMA 5-15P input, the SMART1500CRMXL has an internal battery that provides 14 minutes of support at half load and six minutes at full load. Front-panel LEDs indicate line power, battery power, overload, voltage regulation and battery status. Adding external battery packs, such as Tripp Lite's BP48V24-2U (sold separately), provides extended runtime. Automatic voltage regulation (AVR) maintains 120V nominal output over an input range of 83V to 145V without using battery power. EMI/RFI noise filtering improves your equipment's performance and prevents damage. A 570-joule surge suppression rating protects your equipment from harmful power surges. With Tripp Lite's PowerAlert software (available via free download), SMART1500CRMXL enables safe unattended system shutdown and file saves in case of a prolonged power failure.
