SDHD 400-560KW 3300rpm ±0.2%FS AC Dynamometer for Heavy Duty Diesel
Engine Test
Outline
Very high torques are possible with these electrical machines which
optimally cover the power ranges of medium-size and heavy-duty
diesel engines used in the commercial-vehicle industry. During the
development of the SDHD/SDHD+ series, special importance was
attached to testing. All machine types with associated system
components were tested under extreme conditions. The result is a
very powerful and robust system.
