The Eaton 3S UPS provides effective power protection, even in disturbed electrical environments. The 3S comes with a fixed input cable and 6 Australian outlets for easy connection of typical computer configurations with peripherals. The 3S not only provides a supply with battery backup to keep equipment operating during power cuts, but also provides effective protection against damaging surges. The 3S also protects telephone, broadband and Ethernet line from “back door” power surges. The 3S’s periodic automatic battery testing ensures early detection if a battery needs to be replaced. The easy-to-replace battery helps to extend the UPS service life.
