DESCRIPTION

Xscend, the new shelf based power system from Power-One is designed to meet a broad range of customer applications through flexibility, simplicity and scalability.

Flexible
The Xscend power system offers solutions that meet today's demands by addressing tomorrow's problems, including: power density, reliability, accessibility, upgrades, and space requirements. Utilizing state-of-the art rectifier technology, an integrated microprocessor controller platform and interchangeable distribution modules, the Xscend power system provides a diverse front-access power solution in only a 3 rack unit (5.25in.) vertical and a 300mm (12in.) deep cabinet area. Xscend rectifiers operate using a phase shifted transitional resonant zero-voltage switching technology that offers increased system life and reliability by reducing component stresses. The same engineering strategy gives Xscend the ability to generate up to 1350W in just 3.5-inch (2RU) of vertical space, resulting in a power density of over 9 W/in3. In addition, Xscend's forward thinking horizontal cooling design allows shelves to be placed directly above or below customer equipment, safely increasing the amount of space that can be used for revenue generating equipment and negating the need for airflow clearance above or below the unit.

Simple
The Xscend power system is designed for ease of use through its innovative control and monitoring system. To accomplish this the Xscend is supervised by a single rack unit microprocessor controller (PCS), that offers user-friendly menus and commands that allow an operator to monitor system conditions, capacity, battery parameters and circuit breaker status.

System control can also be accomplished by using an RS485 digital communication bus that allows for remote operation through a Modem, Ethernet (SNMP capable), or standard form C contacts. The PCS controller also works hand-in-hand with the easy to use Power-One POWCOM software package that allows for total system assessment and password controlled parameter adjustments.

Scalable
In keeping with today's unpredictable market requirements, Power-One's Xscend design has targeted a mechanical package approach that permits the power system to expand with ease. Each 23 inch shelf can be fitted with up to five rectifier units delivering up to 125A of system power, while each 19 inch rack can be fitted with up to four rectifiers providing 100A. Additional shelves, distributions and rectifiers can be added to a system offering a high system level density as well as system level modularity providing low start up costs and an easy growth path.
