Provides complete battery backup and power protection for servers, switches and other in-rack IT equipment in small-to-mid-size networks. This SmartPro line-interactive UPS system with AVR provides reliable battery backup and AC power protection against blackouts, brownouts, surges and line noise that can damage valuable electronics or destroy data. The thin, compact SMC1000RT1U is ideal protection for servers, switches, phone systems or Pro AV setups in your small-to-mid-size network closet or computer room where you have a rack with unusual space requirements. The field-replaceable, hot-swappable internal battery provides eight minutes of support at half load (300W) and two minutes at full load (600W), allowing you to work through short power failures and giving you enough time to safely save files and shut down your system in case of a prolonged blackout.
