The SmartPro® line-interactive SMART500RT1U UPS system with AVR protection provides reliable battery backup and AC power protection against blackouts, brownouts, surges and line noise that can damage valuable electronics or destroy data. The 120V battery backup is ideal protection for point-of-sale and kiosk applications, a small business VoIP network, or rack-mount equipment in your server room or network closet. Backup support 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. Backup time varies according to load, but the line-interactive UPS system should keep a half load (150W) powered as long as 14 minutes and a full load (300W) up to three minutes. A 97% efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.Benefits
