Powershield Safeguard 750VA Line Interactive UPS with AVR & USB Port
The Powershield Safeguard 750VA UPS provides a reliable buffer between your equipment and inconsistent mains power supply. This cost-effective, compact device constantly stands guard beside your sensitive equipment, offering 750VA/450W capacity with Automatic Voltage Regulation (AVR) to protect workstations, security systems, and telecommunications equipment from power fluctuations, outages, and surges.
Line Interactive Protection with AVR
The Safeguard 750VA is a line-interactive UPS that provides automatic voltage regulation to correct minor power fluctuations without switching to battery power, extending battery life and ensuring stable output. This UPS is one of the only powerboard-style units with AVR. Anytime a power fluctuation occurs, the UPS will buck or boost the power within a ten percent variance of 240Vac.
