Generator with Digital Technology for uncompromised welding technique
The new Herrmann Ultrasonics DYNAMIC series generator uses state-of-the-art 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
The new digital Generator series utilizes Digital Signal Processing to provide consistent performance independent of component aging or temperature fluctuations. The output signal is no longer affected by the manufacturing tolerances of the build-in components.

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.

Preprogrammed flexibility
Weld time, power draw and weld energy are displayed and monitored on individually programmable windows. A broad array of interfaces includes PLC inputs and outputs via opto-couplers as well as connectors for the DIALOG touch CS controller and a field bus.

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 programming for maximized weld quality
The amplitude can be adjusted from 70-100% to precisely optimize the material and joining characteristics. The digital adaptation of the amplitude eliminates the exchange of the booster and reduces setup time.

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.
