Direct current power distribution system for ITC service provider
The dc technology is said to trim power conversion losses and is 10% to 20% more energy efficient than traditional ac technology for electrical distribution in data centers. The dc systems are also less complex and require less space, reducing equipment, installation, real estate and maintenance costs, resulting in a saving on total facility costs of up to 30%, according to ABB.
ABB will reportedly install a redundant 1 MW dc power distribution solution for the 1,500 m2 expansion of the existing 3,300 m2 data center. It will be designed and engineered to green.ch’s stringent ecological standards by Validus DC Systems, an ABB company. The order includes a service level agreement, and the expansion is scheduled to begin commercial operation in the first quarter of 2012.
Located in the municipality of Lupfig, in north-central Switzerland, the green.ch data center provides customers with secure storage and data management capabilities. The green.ch data center has been selected as ABB’s demonstration site for its new dc technology. It will be used as a showcase for international data center customers seeking to profit from this groundbreaking technology by reaching new benchmarks in energy efficiency for data center technologies, according to ABB.
The project underlines ABB’s goal to expand dc power applications. In May 2011, ABB gained a controlling interest in Validus DC Systems, a leading provider of dc power infrastructure equipment. In 2010, ABB invested in Power Assure, a developer of power management and optimization software for data centers.
