PiezoDrive - Model PDUS210 -210 Watt Ultrasonic Driver / Generator
The PDUS210 is a complete solution for driving and analysing ultrasonic actuators up to 210 Watts. Functions include high-speed resonance tracking of both series and parallel resonance modes, vibration amplitude control, pulsed excitation, frequency modulation, and analysis functions such as impedance and frequency response measurement. The PDUS210 is well suited to both OEM product integration and laboratory use for research and development. Applications include ultrasonic drilling and cutting, cleaning, medical devices, dental devices, ultrasonic testing, cavitation, and vaporization.
The PDUS210 can be controlled from multiple sources including a PC and the included software package, front panel controls, and/or external logic signals from a foot switch for example. An API for external controllers is also available for RS485 and USB connections, which are suitable for automatic test applications and embedded industrial machinery.
The PDUS210 generates a pure sine-wave output which is ideal for operating at the electrical parallel resonance, or ‘anti-resonance’. This operating point is close to the mechanical resonance frequency but is less sensitive to changes in load dissipation, which is useful in precision machining applications where constant vibration amplitude is desired. Current and power control are also available for regulating vibration amplitude at the series resonance mode.
The PDUS210 is available with standard output voltage ranges from 17 Vrms to 282 Vrms, and current ranges from 0.7 Arms to 11 Arms. These ranges are optimized for load impedances ranging from 1.5 Ohms to 400 Ohms at resonance. For research and development applications, a reconfigurable version is available (PDUS210-FLEX), this version uses external output matching transformers to allow operation at any of the available output voltage ranges.
