Description

Protect your electronics with the Eaton 3S850D. This 3S Gen2 unit uses off-line technology to combine the functions of an inverter, lightning arrester, and power strip into one reliable device. It provides effective protection against frequent electrical issues like mains overloads and sudden storms that can disrupt your workspace without warning. When a power failure occurs, the 3S850D automatically switches to battery power. This gives you the necessary time to save your work in progress and shut down your equipment safely. This model also features two USB ports, allowing you to quickly charge your mobile devices. Eaton provides peace of mind with a 2-year guarantee that includes the batteries.
