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 SMART1500RT1U is ideal protection for point-of-sale and kiosk applications, a small-business VoIP network or rack-mount equipment, such as servers and switches, in your server room or network closet.The field-replaceable, hot-swappable internal battery provides eight minutes of support at half load (550W) and two minutes at full load (1100W), 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.Five 5-15R outlets in two separate load banks provide connected equipment with pure sine wave AC output during blackouts, overvoltages and severe brownout conditions. Power provided by these outlets is filtered to protect connected equipment against damaging surges and line noise.
