NOTE: Our dynamometers are constantly being developed, therefore we reserve the right to change the appearance and equipment or technical details of our devices, provided this is reasonable for the customer or the deviations are only insignificant. Shape and color deviations are expressly permitted.

The all-new A330-Series ist replacing the existing A380- and A200-Series.

The dynoKRAFT A200-4WD-ML automotive chassis dynamometer combines affordable price and precise workmanship with best-in-class DAQ system and Software for comprehensive data analysis.

The dynoKRAFT A200-4WD-ML features unique synchronization system.
It combines both mechanic and electronic axis link thus enabling extreme level of synchronization accuracy and dynamics.

Standard installation type is floor-top. Pit installation available on request.

Roller width of 2170mm allow to test even wide-body race cars without problems.

With two 2000Nm eddy current brake the A200-4WD automotive chassis dynamometer allows to test up to 2000HP  (1000HP per axis).
The roller diameter of 515mm reduces tire wear drastically and help keeping the tire temperature under control during long test sessions.

The dynoKRAFT A200-4WD-ML can be freely configured with extension modules (additional inputs, OBD Interface etc…) to match customer needs thanks to our upgradable design concept.
