dynoKRAFT MPS380 PTO / Engine dynamometer

Air-cooled engine dynamometer

Stationary engine test system with wide Torque and RPM coverage.

Features highlight

  • up to 3820 Nm
  • up to 6.300 RPM
  • trailer installation possible

The dynoKRAFT MPS380 stationary engine dynamometer / PTO Tractor dynamometer offers exceptional high measurement precision together with best-in-class DAQ system and high speed Sport Devices PWS-HS Eddy-Current brake power supply.

This affordable dynamometer system can be used to test internal combustion or electric engines. It comes on non-adjustable chassis with stiff test bed allowing vibration-free high RPM testing.

Despite it’s moderate price the dynoKRAFT MPS380 engine test systems offers full test automation and advanced software for data analysis.

For most applications the dynamometer is supplied with high-flexible TOK torsional clutch. Advanced semi-automatic engine docking systems are also available on request.
Please see the technical papers in “Downloads” section.
