To determine whether the control units of their vehicles are working as they should, auto makers rely on testing systems for control devices. The wide range of requirements on these testing systems is reflected in the range of devices developed by Kontron Electronics for such systems. Challenges include high component density, i.e. meeting strict demands on layout and producibility despite constraints in terms of package space. Additionally: separation of power electronics, high current and microelectronics as well as provisions for the 48V onboard power system used in automotive applications.
