SDHD+ 640-800KW 2800rpm ±0.05%FS High Precision Dynamometer for Diesel Engine Test




SDHD / SDHD + dynamometers are especially suitable for heavy duty diesel engine bench. Power dynamometer, bench controller, variable frequency drive and safety module are integrated into a system. The wide application of the system proves that the design is successful. It is suitable for any type of development and functional test bench. The applications range from simple bench for steady-state test to complex bench for dynamic test cycle. Almost every application on a heavy duty diesel engine bench can be realized with a bench equipped with a SDHD / SDHD + dynamometer. The legal test cycle can be simulated
