Designed with simple controls for easy operation, the PowerSure Interactive provides five minutes of battery back-up at full load - more than enough time to save and shut down. With its advanced line-interactive technology, this UPS filters utility power to eliminate spikes, noise and other transients. PowerSure Interactive also contains a voltage "buck and boost" circuit that corrects input voltage as low as 25% below nominal, and as high as 23% above nominal, and does it without switching to battery back-up. This reduces battery demand and increases battery life.Communications-capable via Liebert's IntelliSlot hot-swappable SNMP cards, PowerSure Interactive allows your network management software to treat the UPS as a fully interactive network node. With full SNMP capability, the unit can even handle remote, unmanned shutdown and restart operations.
