A versatile UPS developed for the harshest power conditions in the world . 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. All models 5kVA and above include an integrated Network Management Card for remote management (optional on models below 5 kVA). The Smart-UPS On-Line family provides customers with a reliable source of uninterruptible power even in demanding power environments, including very wide input voltage window, extremely tight output voltage regulation, frequency regulation, internal bypass, and input power factor correction.
