TDK-Lambda power up the Cowboys

Dallas Cowboys are using 22,000 TDK-Lambda ZWS power supplies to light 25 million LEDs on its $40m (€29m) four-sided high definition Mitsubishi Diamond Vision video board. The power supplies have to handle 25 million LEDs.

As part of the team’s move from their previous home in Irving, the recently opened $1.1bn stadium has a retractable roof from which the HDTV screens hang. The four panels, which together weigh 600 metric tons (600,000kg), are suspended approximately 30 metres above midfield. The sideline panel stretches from one 20-yard line to the other and measures 21.76 x 48.32m and has just been recognised by the Guinness Book of Records as the world’s largest High Definition (HD) video screen.

Already Cowboys fans have watched players like Marion Barber, Felix Jones and Tony Romo and, during a recent concert, Sir Paul McCartney adorned the screens. “For high profile installations such as these, the display manufacturer wanted a reliable, quality product to power its LEDs,” said David Norton, vice president of marketing at TDK-Lambda Americas. “That‘s why they chose ZWS power supplies from TDK-Lambda.”
