E-Drive Testing Chamber for external load machine
The EDTC is the chamber solution that is specifically prepared for an external load machine with fixed shaft. Similar to the EMC-BlueBox, the system can be used for dynamic EMC tests of electrical powertrain units in a shielded enclosure. It includes, for instance, braking, driving, direction of rotation (right/left), speed regulation, torque control and a mix out of this range.
Alternatively, the EDTC can be equipped with the HYDROS system which is one of the new powertrain setups using a hydraulic system. An external power converter is outside the chamber and produces the oil pressure to the EUT power converter placed inside the chamber.
The EDTC offers superior conditions for radiated emission testing according to CISPR 25 Ed. 4 and radiated immunity testing according to ISO 11452.
