September, 2005, Tucson, Arizona - C&D Technologies has announced the availability of a new AC/DC front-end power supply. The D1U-W-1600-12-HC delivers up to 1600W (220VAC), 1200W (110VAC) from its 12V output. The 1U high unit has leading power density of 17.5W/cu.in and delivers highly efficient, reliable performance.

Typical applications for the D1U-W-1600-12-HC include blade servers, workstations, storage systems, and any system utilizing a 12V distributed power architecture. The unit uses proven topology and utilizes high-density DC/DC packaging techniques to maximise space efficiency. Planar magnetic devices are used to provide better quality and tighter process control.

The D1U-W-1600-12-HC is available with standby voltages of either 3.3V or 5V. Key features of the comprehensive specification include N+l redundancy, hot-swapability, active current share, an I2C bus, status indicators and over-voltage, over-current and over-temperature protection.

Overall dimensions of the unit are 12.0in. x 4.75in. x 1.6in. Operating temperature range is 0°C to +50°C. The enclosure incorporates cooling fans.

Three D1U-W-1600-12-HC units fit into an optional 1U high 19" wide powershelf, for a total system power of 4,800W.

Kulbir Dhillon, C&D's director for business development, states: "Our engineering team did an outstanding job in leveraging the high density board mount power packaging techniques in this D1U product line. The power density for the output power train is 90 Watts/cubic inch, making it possible for the overall power density to be 17.5 Watts/cubic inch for the power supply. The functional island approach enables flexibility for different output voltages and standby voltages in the product family. The converter topology and component set has proven track record in the field. This D1U product line is optimized electrically, mechanically, thermally to meet our customers' expectations."

Unit pricing for the C&D Technologies D1U-W-1600-12-HC is $438.20 in OEM quantities (USA 1000-piece pricing), and delivery is from stock to 14 weeks.

C&D Technologies, Inc. is a technology company that produces and markets systems for the conversion and storage of electrical power, including telecom/industrial batteries, rectifiers and electronics. This specialised focus has established the company as a leading and valued supplier of products in two major categories - reserve power systems and electronic power supplies. Corporate headquarters are in Blue Bell, Pennsylvania, USA and the company is traded on the NYSE under the symbol 'CHP'.

The Power Electronics Division of C&D Technologies, Inc. has its headquarters in Tucson, Arizona, USA, with manufacturing in USA, Mexico, UK and China plus sales locations in the USA, UK, France, Germany, China and Japan. The division designs, manufactures and distributes DC/DC converters, AC/DC power supplies and magnetics, and offers these products in custom, standard and modified-standard variations. These products, which are built to exacting requirements in ISO9000:2000-approved facilities, are typically used worldwide by Original Equipment Manufacturers (OEMs) within telecommunications, computing, industrial and other high-tech applications.

In 2004 the product portfolio as well as the global design and manufacturing capabilities of the Power Electronics Division were significantly enhanced as a result of three key acquisitions. In May 2004, C&D acquired UK-based Celab Limited, a designer and manufacturer of power conversion products for military, cable television and high-end telecommunications applications. In June 2004, the company acquired Datel, Inc., a US-based producer of medium-power DC/DC converters, data acquisition products and digital panel meters. In September, C&D completed the acquisition of CPS, the former Power Systems Division of Celestica, Inc., a Canadian manufacturer of DC/DC and AC/DC power supplies.
