1 Introduction
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.
2 Safety Warnings
This product produces potentially lethal voltages up to 282 Vrms.
Observe Low-Voltage safety precautions (as per ANSI C84.1-1989), e.g.
● Use an observer trained in low-voltage rescue
● Do not operate with exposed conductors
● Use appropriate signage
