Frontier Dual inverter UPS NOW FEATURES & HOT SYNC TECHNOLOGY
Paralleling for redundancy and capacity increases availability for applications in the 8-100 kVA range

CROSS T.E.C Frontier Dual inverter Division announced today that the latest uninterruptible power system (UPS) in its single-phase product family, the Frontier Dual Inverter, now can be configured for Paralleled solutions using its patented Frontier Hot Sync^® technology. By utilizing Frontier Hot Sync, the Frontier Dual Inverter provides maximum system reliability and availability for applications in the 8-10 range (1 unit) & over model are two units, such as the new technology of double conversion UPS (C.V.C.F)

Parallel redundancy with UPSs has been used for years as a way of delivering higher levels of reliability. If one UPS module must go offline for any reason, there is another UPS to assume the load. In parallel capacity systems, additional modules can be added to increase overall system capacity, allowing a seamless growth path as needs change.

Frontier Dual Inverter Hot Sync is a patented, firmware-based paralleling N+1 technique that has been installed with Frontier Dual Inverter UPS in mission-critical applications around the world. By using a mathematical, not mechanical, approach to paralleling, Frontier Dual Inverter Hot Sync addresses the inherent drawbacks of traditional paralleling configurations as it eliminates the need for communication wiring and added circuitry between the modules. Frontier Dual Inverter Hot Sync also employs unique load share and selective tripping methodology, providing a proven path to maximum reliability and system availability. By bringing this technology to the Frontier Dual Inverter, parallel redundant and parallel capacity solutions are now available in a smaller, three-phase UPS solution.

“Frontier Dual Inverter Hot Sync has been established as the premier paralleling solution in the industry, the already high reliability of the Frontier Dual Inverter, our customers know they will have the highest system availability possible.”

Frontier Dual Inverter Hot Sync Benefits:

l Unlike other paralleling techniques, there is no system-level single-point-of-failure.

l Capable of paralleling for both redundancy and capacity, Frontier Dual Inverter Hot Sync provides a flexible approach to system solutions.

l By using a peer configuration, as opposed to a “master-slave” configuration, Frontier Dual Inverter Hot Sync ensures that each module is operating independently.

l No added circuitry or components are required to be “switched in” to operate in the unit N+1 parallel.

In addition to Frontier Dual Inverter Hot Sync paralleling, the primary features and benefits of the Frontier N+1 Redundant include:

• Double conversion online design – The Frontier Dual Inverter is a true double conversion online design, adhering to IEC (International Electro technical 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.
• High Efficiency – The Frontier Dual Inverter’s advanced design features the highest level of efficiency (C.V.C.F Constant Voltage Constant Frequency) technology of any double conversion online UPS in the 8-10( 1 unit) & over model are two units range with up to 93 percent efficiency. There is no need to compromise reliability for efficiency with the Frontier Dual Inverter.
• Pulse Width Modulation – The Frontier Dual Inverter delivers high performance with fewer components by using digital signal processing, which enables the Frontier Power to offer true pulse width modulation. This provides easy setup, drift-free operation and a more pristine output waveform.
• Intelligent Communications – Using CROSS T.E.C Frontier Power extensive array of communication options, including QuickSNMP^® enterprise monitoring software and QuickCROSS^® foundation equipment monitoring software, the Frontier Power can be managed locally and remotely via direct communications and the network.
• PowerCell XR™ built in battery monitor, featuring:
• Frontier Power Battery Lifetime Monitor uses measures of chronological time, number of battery discharges floating and equalizing, 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 high quality 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 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 – CROSS T.E.C 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. CROSS T.E.C^® Global Service provides customers with peace-of-mind that potential downtime is prevented by taking steps ahead of time.

Frontier Dual Inverter Hot Sync will be available for the Frontier Power in January 2002. For more information on the complete Frontier Power product line and service portfolio capabilities, visit our Web site at http://www.crossups.com or http://www.switchups.com
