Modular UPS extends scalability

Touting an innovative modular approach for very high-power and high-density design, MGE UPS Systems characterizes the scalable architecture of its Galaxy PW line of uninterruptible power supplies as making one of the most robust backup solutions for the IT and critical-process infrastructure.

The Galaxy PW modules, which are field upgradable for 100kVA to 200kVA models, can be combined for capacity or redundancy without any extra paralleling equipment, the company said. Efficiency is 93 percent. Each UPS in a module measures 190.5-by-121.9-by-83.82cm.

Key to the MGE system's size advantage is a "low-kVAR input filter" design with a power factor of >0.9, which limits the reactive current seen by the backup generator. The 225kVA model requires 11 square feet of space, which the company says places it among the industry's highest in power density.

This technology is designed to ensure compatibility with existing generators to improve system reliability and reduce generator oversizing requirements, resulting in significant cost savings.

The system comes with a complement of tools for power management. The company's battery management system with automatic load testing precisely determines battery performance parameters and alerts operators to irregularities before they can affect UPS performance. It also provides predictive failure analysis to alert users when to make a battery change.

Further, the Solution-Pac management software allows users to gracefully control and shut down multiple servers over a network. And with the company's "webi-card" installed, the Galaxy PW can be programmed to issue server shutdown commands via XML tags.

The Galaxy PW is priced starting from $35,000 and includes a one-year warranty.
