EDTC-BB with EMC-BlueBox

E-Drive Testing Chamber with Mobile Load Machine EMC-BlueBox

E-Drive Solutions are Frankonia’s dedicated test sites for powertrain components and facilities related to hybrid, electric, fuel cell and battery drive systems. They offer superior conditions for radiation testing according to CISPR 25 and ISO 11452. The typical chamber is lined with ferrite absorbers and partially lined with Frankosorb® non-combustible hybrid absorbers.

The EDTC-BB is the adapted chamber solution that includes the EMC-BlueBox mobile load machine for dynamic EMC tests of electrical powertrain units in a shielded enclosure. The EMC-BlueBox works in a four-quadrant operation; any EUT stress situation can be simulated. Similar to the external load machine with a fixed shaft, it includes braking, driving, direction of rotation (right/left), speed regulation, torque control and a mix out of this range.
