The SMART1500LCDT is a 10-outlet SmartPro LCD Line-interactive 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 your desktop computer or audio/visual components, this line-interactive UPS switches to battery backup mode in milliseconds to keep your connected equipment running long enough to save files and shut down safely with no data loss. While all ten NEMA 5-15R outlets protect against surges, five outlets also provide up to 90 minutes of UPS battery support for a basic desktop PC and LCD monitor and up to 10 minutes of support at half load (450W). Automatic voltage regulation (AVR) corrects under-voltage as low as 92V and overvoltage as high as 150V without using any battery power. EMI/RFI noise filtering improves your equipment’s performance and prevents damage.
