Application Solutions: Displays and Kiosks

I sometimes get asked by our customers "so what power supply should I use for my application?"  This month we are going to start interlacing our educational articles with some real life examples, and will sort them by the application.

Next time you're going through the drive thru, you may be closer to a TDK-Lambda power supply than you think.  As most drive thru restaurants operate 24 hours a day, 7 days a week, display reliability is paramount.  One recent customer chose the HWS150 series for their application, with the PCB coating "HD" option. The HWS has very conservative component ratings and tested extremely well at ambient temperatures far exceeding the power supply's specifications, simulating abnormal heat wave conditions in desert locations. Convection cooling was also a big plus.
