Putting the Traco Power 450 Series power supplies through their paces

In this short video, Executive Editor Lee Teschler and Senior Editor Lisa Eitel power up a couple of power supplies from Traco Power in Switzerland and watch some of the things they can do. One supply is an open frame model in a power-dense 3×5-inch footprint. The other is enclosed. We’ve powered up the open-frame model and set it up with a dummy load to get a feel for how it performs. The open frame version we’ve powered up also has the ability to run a 12-volt fan via a fan connection available on an auxiliary connector.
