SiC Schottkys in UPSs for North American Data Centers

Fuji Electric Corp. of America has announced that they have developed their next generation UPS System for the North American data center market. The manufacturer's new UPS7300WX-T3U is an innovative transformer-less UPS designed to withstand the specific load and environmental conditions of data centers as well as other commercial applications, utilizing Fuji Electric's own patented RB-IGBT Technology and AT-NPC 3-Level Circuit Topology to deliver up to 97.5% efficiency and unparalleled reliability. The series is the company's most scalable UPS system to date, with expandable architecture that delivers any size unit from 225- to 1000-kW using 330kVA modules.

The UPS7300WX-T3U series will be rolled out in phases beginning in January 2017, followed by additional product releases in July 2017 and December 2017. The IGBT modules used in the UPS7300WX-T3U unit were specifically designed for use in commercial applications, and include SiC Schottky diodes in combination with Fuji’s low-loss V Series IGBTs. The systems rely on dc-dc converters for battery longevity and offer selectable High Efficiency (HE) mode for superior efficiency when power conditioning is not required, thereby increasing the efficiency to as high as 99% under normal conditions.

“Our Engineering team recognized that data centers value scalability in their equipment, particularly the UPS systems, so that their infrastructure can grow with them,” said Phil Charatz, President and CEO of Fuji Electric Corp. of America. “The UPS7300WX-T3U series offers this flexibility, along with other key features such as High Efficiency mode and the use of advanced materials contributing to the unit’s durability and efficiency.”

Redundant fans come standard with all UPS7300WX-T3U models, and the units are fully maintainable and repairable with only front access required. Equipped with large color touch screens and convenient at-a-glance status LEDs, these UPS systems also come with Fuji Electric’s industry-leading three-year warranty for reduced total cost of ownership.

“Data centers have become more advanced and complex in recent years, and it’s critical that the equipment supporting these facilities be held to the highest standards in terms of quality and reliability,” added Mr. Charatz. “Fuji Electric has been manufacturing power electronics products for nearly a century, so our customers can rest assured that our UPS systems will offer them the protection they need when it counts the most.”
