Smart-UPS On-Line provides high density, true double-conversion on-line power protection for servers, voice / data networks, medical labs, and light industrial applications. Capable of supporting loads from 1 to 20kVA in a rack/tower convertible form, the Smart-UPS On-Line is available from 2U to 12U. Recent family extensions at 15 and 20kVA enable support of power hungry blade servers or heavily loaded equipment racks. When business-critical systems require runtime in hours, not minutes, Smart-UPS On-Line can be configured with matching battery packs to comply with aggressive runtime demands. The included PowerChute management software provides unattended graceful shutdown of network operating systems.
