ABB QUESTIONNAIRE FOR PULSED POWER APPLICATIONS

Working in an area where new system designs and experimental systems are invented, we know how difficult it is for the designer and the supplier of components to select the right parts for the application.

Because the selection of components is not based on datasheet figures, ABB Semiconductors AG is offering a service to support customers with the selection of the right component, or switch assembly.
