SiC Enhances UPS Efficiency, Performance and Reliability

Mitsubishi Electric announced its latest three-phase UPS, known as the SUMMIT Series. This new UPS incorporates SiC devices to replace the IGBTs. Silicon carbide possesses many attractive traits as a power device, including higher switching frequencies and lower switching losses. In addition, silicon carbide inherently offers higher thermal conductivity, thereby promoting heat dissipation. These characteristics make silicon carbide the material of choice for semiconductors within the power industry.

Designed for data centers and other demanding mission-critical applications, the SUMMIT Series UPS is currently offered in 500kVA with plans to introduce a 750kVA model in the near future. Offering efficiency greater than 98 percent at 50 percent load with a maximum efficiency 98.2 percent, the 500kVA UPS is a three-phase, on-line double-conversion system that supplies clean, continuous power to systems sensitive to fluctuations common in utility power.

Higher efficiency translate to lower energy usage and cooling costs, and also contribute to a lower total cost of ownership. Like other Mitsubishi Electric UPS products, the SUMMIT Series is lighter in weight than competitors’ products and has a minimal footprint, which allows data center owners to maximize floor space.

“The new SUMMIT Series truly is a game changer in our industry,” said Dean Datre, general manager, Mitsubishi Electric Power Products’ UPS Division. “The robust SiC semiconductor used to power the UPS modules takes performance and reliability to a previously unattainable level.”

The SUMMIT Series UPS is available now and is fully supported by Mitsubishi Electric Power Products, Inc.’s factory–direct, 24x7x365 services, training, and application expertise, as well as a three-year parts and labor warranty.
