Magnetek Unveils Highest Power-Density Front-End Converter

Chatsworth, CA, July19, 2006 -- Magnetek, Inc (NYSE: MAG) today introduced the highest power-density “front-end” power supply available for energy-intensive applications. The Company’s new HPD-800™ converter packs 800 watts of 12-volt Dc power into a package 9.84 inches long by 2.36 inches wide by 1.65 inches deep, equating to over 20 watts per cubic inch.

Such high power density is unprecedented in front-end power supplies. In addition, the HPD-800 provides power conversion efficiency in excess of 90% under full load at 230 volts Ac input, minimizing energy consumption as well as system size in broadband, data storage and other power-hungry installations.

Integral air cooling enables HPD-800 converters to operate reliably in ambient temperatures up to 50˚C over a wide Ac input range (85 to 264 volts), delivering 67 amps of 12-volt Dc output in distributed power architecture systems. Operating singly or in parallel, their ultra-compact “1U” form factor and “hot plug” ability facilitate “hot swap” system design flexibility, while I2C (or optional RS485) communications afford completely automatic remote system monitoring and control.
