Matrix signs are commonplace up and down our nation’s motorways advising us on such things as traffic jams and incidents up ahead or to slow down to avoid unnecessary traffic build-up. As with all traffic signage, high reliability and robustness in all weather conditions are essential as failure in the field is not an option. For this particular application, one manufacturer chose the fanless, baseplate cooled PFE range of ac-dc power modules from TDK-Lambda and, working closely with the technical support team, developed a special assembly that fulfilled all of the requirements specified in its demanding design criteria.
