Roadside Variable Message Signs

Posted by Dulcie on January 27, 2015

Traffic variable message signs are subjected to all the elements of weather. TDK-Lambda’s 50W and 150W HWS-A series of power supplies was selected by one sign manufacturer not only for having a limited lifetime warranty, but by using the /HD models, the product is guaranteed to start up at -40oC.
