Digital Signal Processor Power Supply for Ultrasonic Welders

A new digital signal processor power supply is being launched by Sonics & Materials for its line of ultrasonic plastic welding equipment. Model DX800 has been added to the company’s DX Series OEM DSP (digital signal processor), and is said to offer energy savings, increased throughput with faster welds, and advanced data capture and control.

This state-of-the-art DSP-controlled power supply is able to scan the ultrasonic stack (converter/booster/horn) to determine the optimal starting frequency. The result is said to be increased success with difficult ultrasonic horns, such as those with an irregular or nonsymmetrical shape, multiple frequencies or wearing from long-term use and difficult applications. Start modes are also available in “last frequency” mode and user-defined mode, with phase offset automatically adjusting operating frequency for high load conditions.

The DX800 offers time and energy control with an LED bar graph for easy-to-view activity monitoring and error status. Predictive maintenance and machine learning algorithms can be implemented by a hosting system, and the power supply has three communication protocols available to configure or log data (USB, Ethernet I/P and PLC I/O).
