Digital Technology for uncompromised Performance

The new Herrmann Ultrasonics DYNAMIC series generator uses state-of-the-art digital control technology to perform independent of component aging or temperature fluctuations. In addition, comprehensive programming allows intelligent adaptation of the weld parameters to different acoustic stacks.

State-of-the-art DIGITAL SIGNAL PROCESSING

A intelligent Digital Signal Processing system supports self-learning, and a reliable long term memory allows storage and recall of all important weld parameters.

RESONANCE SCAN frequency matching for optimum performance

The new DYNAMIC digital control generators recognize the resonance frequency of the Converter/Booster/Horn Stack and automatically adjust to its start-up characteristics. This provides protection against weld horn damage and insures that the entire system always operates with optimum efficiency. All weld horn data can be stored to allow "plug-and-play" weld horn stack exchange. In addition, because of this precise frequency tuning feature, the new DYNAMIC digital control generators can operate weld horns within an extreme narrow frequency band.

DYNAMIC digital control for reproducible welding results

A digital control loop continuously monitors the performance of the converter/booster/horn assembly to provide optimum efficiency. Temperature fluctuations and weld horn wear are automatically compensated. Constant amplitude is maintained independent of line voltage fluctuations.

Amplitude consistency even with fluctuating line voltage

Line voltage variations directly influence the amplitude of the weld horn, resulting in inconsistent weld quality. An intelligent closed-loop circuit automatically compensates for voltage variations of + 10% to - 15% throughout the output range of the generator. This feature is critical for achieving repeatable weld results during unstable operating voltage conditions.
