MGE compact UPSs boost power density

With across-the-board space and power density issues continuing to drive power conversion, MGE UPS Systems bills its new Pulsar Evolution family of UPS as the smallest, most powerful UPS in its class.

Rated at up to 1.1kVA in a 1U-size rack-mount enclosure (maximum 43.9-by-436.9-by-497.8mm, about 35 pounds), the line-interactive UPSs do away with the bulky transformer used in other designs, essentially providing double the power density of most 1U competitors. They are intended for servers, storage systems and networking equipment. Three models (500VA, 800VA and 1.1kVA) are also available in tower versions

At 800VA and 1.1kVA (149.8-by-236.2-by-414mm, about 25 pounds), its features include hot-swappable (lead-acid) batteries that are user-replaceable from the front of the module, and a standard USB as well as a serial port for local- or remote-network power administration. It also has four receptacles, with two having a so-called power share facility for selectively powering products during a shutdown.

The Evolution will keep a hub, switch and router up for 45min or a Windows 2000/NT server on for up to 25min (depending on server configuration), allowing users to ride through most power disturbances or to allow for an orderly shutdown during prolonged power blackouts.

It delivers a sine wave output. It's designed to tolerate wide voltage variations at the input (150V to 294V), particularly important in fluctuating power environments.

Advanced charging algorithms extend battery life up to 50 percent, and smart-battery management assures advanced warning for battery replacement. Power administration is handled through the unit's USB and serial ports in conjunction with the company's Solution-Pac power-management software for Windows 95/98/2000/NT, Novel NetWare, SCO Unix v. 30, SCO Openserver 5.0 and Linux.

The software provides power management for one or more servers as well as Simple Network Management Protocol or Web-based remote monitoring. It uses a GUI for automatic, orderly shutdown of unattended servers during extended outages and for automatic reboot, remote monitoring and alarm notification via e-mail, fax and pager.

Pricing starts at $297 for the Evolution 500 rack mount, $407 for the Evolution 800 and $535 for the Evolution 1100. Tower versions at 800VA and 1.1kVA sell for $322 and $509, respectively.
