With high-density and expanded flexibility in mind, the Evolution series of uninterruptible power supplies by MGE Office Protection Systems sets claim as the first line-interactive family in its class with a space-saving, multiposition power distribution unit (PDU) for adding receptacles to the back, side, or top of the UPS. In addition, optional universal HotSwap Maintenance By-Pass modules and included software allow the UPS to support up to 15 servers without interrupting service.

Evolution 650/850/1150/1550 and 2000-VA models feature multiple form factors for dense tower and rack/tower applications, including a choice of depth sizes. They are available in 1U- and 2U-high units, and the 3U "short-depth" 3-kVA unit accommodates the usually shallow telecom racks/enclosures now employed for densely packed IT systems.

On the other hand, the Evolution S 1250/1750/2500 and 3000-VA models are suited to critical applications requiring extended runtime. They can accommodate up to four external battery modules, which will keep a Windows 2000/NT/2003 server going for up to 145 minutes at 100 percent load.

Microprocessor-controlled charging extends battery life up to 50 percent, while smart-battery management protects against deep discharging and assures advanced warning when the hot-swappable batteries eventually need replacement.

These line-interactive units provide a clean sinewave output, according to the company, as well as wide input voltage tolerances (especially important in fluctuating power environments). The company's Powershare technology provides two programmable outlets on the Evolution units that can be used to quickly reset network devices remotely and allocate longer backup times to the most critical equipment. "Cold-start" functionality allows users to turn on the UPS and connect equipment even after the power has failed.

Local and remote network power administration is handled through the unit's USB and serial ports with the company's Solution-Pac power management software for Windows, Linux, UNIX, and MacOS. Solution-Pac provides advanced power management for enterprise-wide servers as well as SNMP or Web-based remote monitoring. With an intuitive graphical interface, the software guarantees automatic orderly shutdown of unattended servers during extended outages, automatic reboot, remote monitoring, and alarm condition notification via e-mail, fax and pager.

Network integration with HP OpenView, IBM Netview, CA Unicenter, and HP Insight Manager is handled with an optional network management card. Each Evolution UPS comes with a free version of Enterprise Power Manager to manage up to five UPSes or other power devices (PDUs, PoE midspans), regardless of brand. Additional optional communications solutions are also available, including network management cards, environmental sensors, and remote displays.

The Evolutions' feature a power factor of 0.9, and thus the UPSes are properly sized to protect blade servers and the like with power-factor-corrected (PFC) power supplies.

Now available, the Evolution models start at $314 list and include a complete package including Solution-Pac power management software, Enterprise Power Management software for five nodes, and all cables, rails, brackets and a screwdriver. The systems feature a comprehensive two-year warranty that includes battery replacement. Extended warranties are available to provide a total of 3 or 5 years of coverage.
