Overview
The PDUS210 is a complete solution for driving precision and high-power ultrasonic actuators.
Functions include high-speed resonance tracking of both series or parallel resonance modes,
vibration amplitude control, 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, medical devices,
dental devices, ultrasonic testing, liquid cavitation, and vaporization.
The PDUS210 is controlled via USB and the included software package. An RS485 interface also
provides a straight-forward method to control and monitor the amplifier for automatic test and OEM
applications.
The PDUS210 generates a pure sine-wave output which avoids the excitation of secondary
resonance modes by the drive harmonics. This makes it 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.
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.
