Maurizio Salato to present two technical papers at INTELEC 2013

Vicor’s director of systems engineering, Maurizio Salato, will present technical papers discussing 380/400 VDC distribution for telecom and datacenter power applications during INTELEC® 2013. These presentations, which are part of the High Voltage DC technical program, were co-written with other leading power experts from across the industry. The first paper, “380 VDC Ecosystem Development: Present Status and Future Challenges” will be presented with representatives from HP, Universal Electric Corporation, Juniper Networks and Emerson Network Power. Attendees will hear an overview and progress update about the ecosystem development and future direction for 380 VDC distribution...

Optimizing for Datacenter Power System Efficiency and Reduced Energy Costs

Optimizing for Datacenter Power System Efficiency and Reduced Energy Costs

There are no sloppy designs in datacenters. To the consumer a datacenter is just another pipe in the cloud, a conduit for their data and experiences.  However, to the industry giants wringing real dollars (in the form of demographic studies, transactional charges, and raw click-based advertising) a datacenter is the backbone of their business operations. Just like the assembly lines of Ford and the coke furnaces of Carnegie, the most efficient (least cost to operate) datacenter provides the greatest set of financial and operational benefits to their owners.

At PCIM Europe 2013, Vicor presented a paper describing how “Central Offices” for Telecommunications have been historically powered by a wide range, negative-referenced 48V distribution system. The need for simple, direct battery-power backup has been the main driver behind this choice, which is regulated by global organizations standards.

48 Vdc Distribution; a Safe, Practical and Efficient Solution for Equipment Racks

Vicor’s new AC Front End Module has an isolated, regulated output of 330 W at 48 Vdc. Its applications are many and varied, including powering rack-mounted equipment in telecommunications or data centres. However designers for such applications sometimes ask why the DC output has been set at 48 V rather than 12 V, or even 5 V?
