ColdWatt Expands Power Conversion Platform To Include Blade Server Product Applications

October 18, 2007 by Jeff Shepard

ColdWatt Inc. has expanded its digital power conversion portfolio to include platforms aimed at blade and high end server architectures, as well as rack-optimized servers.

ColdWatt’s second generation products, the 1625W power supply and 750W power sub-system, are claimed to pack high efficiency and industry-leading density in a compact form factor that surpasses industry efficiency-level targets. ColdWatt claims that IT equipment vendors can decrease their operational expenditures and help their server customers achieve their green IT goals.

The dense form factor of ColdWatt’s 1625W power supply is suitable for blade applications that strive for high performance density. ColdWatt’s 1U 750W ac-dc power subsystem is designed with a narrow form factor and what is described as superior power density, allowing customers in the sub-$25K server market to achieve better thermal performance and improved data center efficiency compared to commodity power solutions.

"At ColdWatt, we are manically focused on delivering products that enable cost-conscious OEMs to leapfrog their competition with cutting edge performance density and lower overall power consumption," said Joe Lamoreux, ColdWatt’s CEO. "Our 1625 and 750W solutions have been designed with customer applications in mind to maximize efficiency across a wide load range and deliver the most useable power, resulting in lower total cost of ownership for IT equipment manufacturers."

ColdWatt’s 1625W power module delivers 90% efficiency with a power density of >18W per cubic inch, simplifying thermal management and delivering more useable power than competing solutions. The 1625W power supply includes ColdWatt’s "Black Box" feature, which enables system designers to deliver increased reliability and traceability for end users. Critical power parameters such as Vin, Vout and temperature are continuously monitored and stored at the time of a fault for retrieval and post processing.

ColdWatt’s 1U 750W ac-dc power subsystem is designed with a narrow form factor to deliver superior power density and >90% efficiency at >20% load. It is form-factor compatible with the 650W ac-dc power subsystem, allowing existing customers to scale up their designs with new features and leverage their existing power sub-system design. Using ColdWatt’s redundant power subsystem, designers are said to be able to increase the reliability of their systems and provide dense server configurations, while addressing the demanding space, heat and cost factors of today’s rapidly evolving server environments. The company claims that hermal management is simplified and data center efficiency is significantly improved compared to commodity power solutions.
