• Four-wheel drive single roller dynamometer for cars with axle load of 2400 kg, includes two eddy-current brakes on the rear axle with an electric motor and an eddy-current brake on the front axle with an electric motor, ideally suited for performance measurements, tuning and diagnostic work on very powerful vehicles
  • Test speeds of up to 300 km/h
  • Tyre rolling action as it would be on the road
  • Tyres are preserved as a result of limited flexing action
  • Simple restraining mechanism for quick vehicle fixation
  • Electronically-controlled synchronisation of the speed of the front and rear roller set for current and future drive concepts with active power distribution

High level of flexibility in use due to extensive variety of operating modes, covering all fields of application:

  • Static power measurement at constant RPM
  • Static power measurement at constant speed
  • Static power measurement at constant tractive force
  • Dynamic power measurement with adjustable acceleration
  • MAHA towing power measurement guarantees the highest degree of accuracy when measuring power:
    Precision calculation of the parasitic losses of the dynamometer, of the vehicle’s drive train and the tyre to roller friction and flex losses Tachometer testing with up to ten freely selectable test points
  • Distance measurement included
  • Stopwatch function for measurement of acceleration between optional speed markers as standard
  • Optional load simulation with freely programmable load profile
  • Optional driving simulation with freely programmable speed profile
  • Option of storing programmed profiles in database

Professional, intuitive-use software for the highest expert standards with:

  • continuous graphic display and recording of up to 16 freely selectable parameters per performance measurement cycle on one measurement screen.
  • In addition to the current performance measurement cycle, fade-in of up to three stored cycles on the measurement screen for optimum comparability during calibration work
  • Two circular dial displays for RPM and speed as well as current oil temperature display, ensuring constant control of key parameters during performance measurement
  • Determination of wheel power, power dissipation, engine power and torque
  • Standardised extrapolation of motor power in line with DIN 70020, EEC 80/1269, ISO 1585, JIS D 1001 and SAE J 1349 (configuration-dependent)
  • Circular dial display of motor power, RPM, speed and tractive force during simulation cycles
  • Colour-highlighted user prompts integrated within the circular dial facilitate the accurate reproduction of simulation cycles
  • With radio remote control as standard for complete control of the dynamometer from within the vehicle.
  • Radio remote control with long-life battery and charging station
  • Cooling fan switched on and off either at the control console or with the radio remote control
  • With interface box including stand and long connection cable as standard for optimum placement at the dynamometer with MAHA plug-in CAN-DRZ module card for connecting RPM sensor.
  • Interface box optionally upgradeable with MAHA plug-in card for comprehensive recording of external Ambient data such as air temperature, air pressure, rel. humidity and intake temperature
  • Interface box optionally upgradeable with MAHA plug-in analogue input module card with 4 sensor inputs for temperature and pressure sensors or lambda sensors.
  • Optional connection of MAHA MGT 5, MDO 2 LON and MET SERIES emission testers
  • Optional connection of Krupp/AIC fuel consumption measuring instruments for petrol- and diesel engines
