Tripp Lite series SmartOnline 1500VA 1350W 120V Double-Conversion UPS - 8 Outlets, Extended Run, Network Card Option, LCD, USB, DB9, 2U Rack/Tower, TAA. This SmartOnline UPS system provides uninterrupted battery backup and AC power protection against blackouts, brownouts, surges and line noise that can damage valuable IT equipment or destroy data. Its on-line double-conversion topology continuously conditions incoming power and provides zero transfer time to battery during outages, which ensures clean, consistent sine wave output. It’s ideal for education, healthcare, military, government and other mission-critical IT applications where space is limited, but premium power reliability is essential. The field-replaceable, hot-swappable valve regulated lead acid (VRLA) battery allows you to work through short power failures and gives you enough time to safely save files and shut down your system in case of a prolonged blackout. Automatic restart after power outages reduces costly on-site visits.
