DYNAS3 dynamometers are specially designed for use in engine test stands. The combination of the powerful DYNAS AC machine with a variable frequency drive, fine-tuned test stand controller and proven safety module produces reliable and accurate results. The dynamometers can be used in any type of development and function test stand. There is a wide range of applications for steady-state and dynamic operation, such as the simulation of legislative test cycles as well as Road Load Simulation (RLS) including driver and vehicle simulation.
