Eaton’s 9390IT UPS Double-Conversion Design

Date: June 1, 2009

RALEIGH, N.C. … Diversified industrial manufacturer Eaton Corporation today announced the availability of the Eaton 9390IT uninterruptible power system (UPS) with double-conversion technology that protects Information Technology (IT) equipment from the most common utility power problems. As the latest addition to Eaton’s three-phase product family, the 9390IT offers the industry’s smallest footprint at 40 kVA, up to 61 percent smaller than competitive units. This helps to save valuable data center space, and the 40 kVA modular building block concept provides a cost-effective solution for growth. The 9390IT’s compact footprint is attributed to its transformer-less design and standard internal batteries, which eliminate the need for costly and space-consuming external battery cabinets. With Eaton’s Energy Saver Mode, the 9390IT delivers an efficiency of 99 percent with double-conversion protection. In addition to the cost savings, this enhanced efficiency extends battery runtimes and produces cooler UPS operating temperatures, extending component life and increasing reliability and performance. “With shrinking IT budgets, data center managers are seeking a backup power solution that gives them the most for their investment. The 9390IT comes well-configured with many standard features,” said Dave Pisano, Eaton 9390IT product manager. “With the 9390IT, the proven and reliable Eaton 9390 UPS platform is now available to all Eaton sales channels with several notable enhancements, including internal batteries, built-in maintenance bypass, high efficiency and a modular scalability that allows the 9390IT to grow as needed, without costly wiring and other facilities expenses.”

As a pre-wired, integrated module, the 9390IT saves time, installation cost and cabling expenses because of its standard top or bottom entry design. Also, at the heart of its efficient design is the on-board, pre-wired and fully integrated maintenance bypass, or parallel tie side-car, which makes it convenient to service the UPS without disruption to critical loads. Eaton’s use of sustainable materials and highly efficient manufacturing technology results in a dramatic carbon footprint reduction compared to competitive UPS products. In an environment of higher energy costs, rising emissions concerns and rapid global growth, Eaton’s innovative technologies help customers use power more efficiently.
