Validus DC Systems Launches End-to-End DC Power Infrastructure for Mission-Critical Data Centers

Substantial Energy-Efficiency, Reliability and TCO Benefits Lead to First Commercial Deployment at Major Financial Services Institution

BROOKFIELD, CT--(Marketwire - January 28, 2008) - Validus DC Systems, a leading provider of integrated DC power infrastructures for data centers and telecommunication facilities, today announced the wide availability of its complete family of DC products that reliably and efficiently distributes direct current (DC) power throughout mission-critical facilities. Validus' end-to-end solution is the first-ever, fully-integrated DC power infrastructure that delivers immediate energy-efficiency and reliability benefits along with significant long-term operational cost savings.

By eliminating the inefficiencies inherent in legacy AC power infrastructures such as multiple energy-wasting power conversions, transformations and unnecessary heat-producing components needed for AC system reliability, Validus' DC power infrastructure enables customers to increase processing power and server densities in new and existing facilities at a lower total cost of ownership (TCO) while reducing complexity, downtime, and power and cooling costs. Additionally, Validus' "Hybrid Power" technology is designed to work alongside legacy AC systems, which allows customers to migrate from lower density AC infrastructures to higher density DC topologies at their own pace.

"The ability to efficiently scale and distribute DC power throughout the data center marks a paradigm shift for businesses struggling to handle the escalating power, performance and reliability demands of today's data center," said Rudy Kraus, CEO and founder, Validus DC Systems. "Validus' safe, reliable and modular end-to-end DC power solution overcomes all the traditional barriers to distributing DC power in the data center, and can help companies achieve greater levels of data center performance and yield up to a 40 percent improvement in energy efficiency."

Optimum Data Center Efficiency

Compared with typical AC powered data centers with the same server processing capability, a Validus DC powered data center can save up to 50 percent of the raised floor space and significantly reduce the total energy consumption required for server power and cooling. Recognizing these substantial benefits, a leading global financial services firm headquartered in New York, NY is deploying the first commercial Validus DC System in one of their mission-critical data centers.

"Validus has made DC power a viable, simple solution for customers looking to substantially increase the overall efficiency and reduce the operational costs of their data center," said Timothy M. Doherty, Chief Operating Officer, Mzima Networks. "With an end-to-end DC power infrastructure available today that can work alongside traditional AC power systems, Validus will help push DC power into the mainstream data center."

Making DC Power a Reality

In a typical system design, Validus' end-to-end solution begins with the Power Quality Module (PQM), which is an air-cooled, mission-critical grade rectification system that converts alternating current (AC) power from the utility to high voltage (-575 V) DC power.

From the PQM, high-voltage DC power is fed to the Power Distribution Module (PDM-575), which acts as a common interface for all system components in the power infrastructure of the data center. The PDM-575 is a scalable switchboard that simply integrates and controls power distribution from multiple system inputs such as the utility, stored energy devices, photovoltaic systems, distributed generation equipment, wind turbines and batteries and provides the necessary critical load distribution of -575 VDC power to the Power Converter Units (PCU).

The enabling component of Validus' DC power solution is the revolutionary Power Converter Unit (PCU) 120, which uses patented technology to efficiently convert -575 VDC to safe, usable -54 VDC power, distributing 120 KW of power to the server row. Located at the mid-point of each server row, the PCU-120 consists of four (4) 30 KW integrated, hot-swappable Power Converter Modules, (PCM-030), which are highly efficient power conversion devices that deliver regulated output to power any load demand up to 120 KW per PCU. An optional Power Distribution Module (PDM-055) designed specifically to distribute low voltage DC power short distances mounts adjacent to the PCU-120 and delivers -54 VDC to the point of use (server rack).

Normal or stored energy power in the Validus DC solution can be provided by batteries, photovoltaic devices, wind turbines, fuel cells, fly wheels or any DC source with the proper voltage. Typical modular battery cabinets with a battery charging system can be seamlessly integrated into the PDM-575 offering the equivalent functionality of a UPS system. The standard PBS battery cabinet system supports predefined battery backup run time and utilizes a ten year "maintenance free" battery system in a stand-alone or parallel configuration. Validus' PQX is an air-cooled, AC powered, stand-alone battery charging system that includes an interactive LCD display for monitoring information and an automatic restart after a high-voltage shutdown event.

Global Support

Validus also recently announced a global services and support partnership with Siemens Energy & Automation, Inc. that will provide customers 24 x 7 x 365 emergency response, start up and commissioning services, preventative maintenance and an array of equipment monitoring solutions, in addition to Validus' dedicated in-house engineering and technical support team.
