The SMART1000RM1UN SmartPro 120V 1kVA 800W 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 data centers, VoIP systems and network closets, the SMART1000RM1UN switches to 1kVA/800W battery mode in milliseconds to keep your connected equipment running long enough to save files and shut down safely with no data loss. Two of the six NEMA 5-15R outlets may be switched off remotely to reboot equipment or shed nonessential loads to maximize battery backup time for mission-critical equipment. The internal battery provides 14 minutes of support at half load (400W) and four minutes at full load (800W). Network Management Card accessory card comes pre-installed to permit remote management of the UPS. Automatic voltage regulation (AVR) maintains 120V nominal output over an input range of 83V to 147V without using battery power. EMI/RFI noise filtering improves your equipment's performance and prevents damage. A 450-joule surge suppression rating protects your equipment from harmful power surges. With Tripp Lite's PowerAlert® software, available via free download, the SMART1000RM1UN enables safe unattended system shutdown and file saves in case of a prolonged power failure.
