RALEIGH, N.C. (October 15, 2001) Invensys Powerware Division announced today that the latest uninterruptible power system (UPS) in its Series 9 product family, the Powerware 9330 Model 40, for solutions in the 20-40 kVA range, is now available.

In today's e-business economy, systems availability is critical for daily business operations, communicating with customers and suppliers, and sharing information. When systems are down, business halts, translating to lost productivity and lost revenues.

Designed to meet the high-availability needs of these critical 24/7 applications, the Powerware 9330 delivers enhanced systems reliability and one of the highest efficiency ratings of any online UPS available today. The 9330 also contains high-end features and benefits that only existed in larger capacity UPS until now. The 9330 complements a new breed of IT solutions, including the new IBM pSeries 690 UNIX server, a high performance server created specifically as an e-business "infrastructure in a box."

Power technology has emerged as a critical element of an enterprise's infrastructure, according to The Meta Group in a 1999 report on "The 21st Century Data Center." This means that IT managers must implement the most efficient solutions possible, without compromising the business need for availability. Through its well-thought-out design, the Powerware 9330 helps IT managers meet both the high availability and operational efficiency requirements they face by eliminating a primary cause of downtime: power problems.

"E-business has changed the way even minimal downtime can dramatically impact the bottom line," said Darrick Finan, director of product marketing, Powerware. "Features that have made the Powerware brand the leader in high-end, three-phase UPSs for e-business clients like E*Trade, AboveNet, CitiBank and Goldman Sachs, are integrated into the Powerware 9330, making it the most reliable UPS in this power range."

The primary features and benefits of the Powerware 9330 include: Double conversion online design - The Powerware 9330 is a true double conversion online design, adhering to IEC (International Electrotechnical Commission) standard 62040-3. Double conversion online is the proven technology that is used for the most mission-critical applications in the world. It's virtually impossible to find line-interactive, "pseudo-online" or any other kind of UPS other than double conversion online supporting 24/365 data centers, facilities, ISPs and major telecommunications installations.

Powerware Hot Sync - With Powerware Hot Sync, the award-winning, patented technology that achieves paralleling for redundancy and capacity (up to four modules) with no system-level-single-point-of-failure. The preferred paralleling technology installed around the world, Powerware Hot Sync will be available in the 20-40 kVA range with the Powerware 9330 in the fall of 2001.

High Efficiency - The Powerware 9330's advanced design features the highest level of efficiency of any double conversion online UPS in the 20-40kVA range with up to 93% efficiency. There is no need to compromise reliability for efficiency with the Powerware 9330.

Pulse Width Modulation - The Powerware 9330 delivers high performance with fewer components by using Digital Signal Processing, which enables the Powerware 9330 to offer true Pulse Width Modulation. This provides easy setup, drift-free operation and a more pristine output waveform.

Intelligent Communications - Using Invensys Power System's extensive array of communication options, including PowerVision enterprise monitoring software and FORESEER foundation equipment monitoring software, the Powerware 9330 can be managed locally and remotely via direct communications and the network.

DC Expert Plus - built in battery monitor, featuring: Powerware Battery Lifetime Monitor uses measures of chronological time, number of battery discharges, battery temperature, and system loading to determine runtime remaining and battery lifetime remaining.

Battery Runtime Remaining Monitor uses system loading plus internal sensing points for voltage and current data to calculate runtime remaining.

Advanced Battery Management (ABM) uses patented three-stage charging technique that not only doubles battery service life, but also optimizes recharge time.

Battery Circuit Test (BCT) performs a periodic pulse test of the battery string to ensure that there are no open circuits that would jeopardize battery performance and system availability.

Temperature Compensated Charging (TCC) monitors the battery temperature and through sophisticated algorithms adjusts the rate of charge, compensating for the ambient temperature to prolong the life of the battery.

Global Services - Invensys Power Systems professionals provide around-the-clock monitoring, remote diagnostics, and on-site maintenance programs. More than just a warranty, this is the most comprehensive service coverage available in the industry. Powerware Global Service provides our customers with peace-of-mind that potential downtime is prevented by taking steps ahead of time.

The Powerware 9330 Model 40 (20-40 kVA) is available now, starting at less than $15,000 for 20kVA and includes 12 minutes of internal battery run-time.
