The SM1500RMXL2UTAA is a 8-outlet 1kW line interactive sine wave Uninterruptible Power Supply (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 SM1500RMXL2UTAA switches to 1.5kVA/1.35kW battery mode in milliseconds to keep your connected equipment running long enough to save files and shut down safely with no data loss. Four of the eight 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 (675W) and 4.9 minutes at full load(1.35kW). Adding optional external battery packs, such as Tripp Lite’s BP36V15-2U, provides extended runtime.
