The EDTC is Frankonia’s fully compliant e-drive and powertrain testing chamber solution that is designed for EMC components and system testing for all types of hybrid, electric, fuel cell and battery drive systems. The term powertrain describes the main components that generate power and deliver it to the road, water or air. With its innovative concept and its optimized layout that is based on the ACTC (automotive components testing chamber), the EDTC offers superior conditions for radiation testing according to CISPR 25 and DIN/ISO 11452-2, and remarkable minimized reflections. The chamber is lined with ferrite absorbers and partially lined with Frankosorb® hybrid absorbers to cover a frequency range from 150 kHz to 18 GHz (40 GHz as option) that offers outstanding performance.
