January 31, 2019 –PI (Physik Instrumente) LP has released the model E-619, a piezo amplifier designed to drive high-capacitance multilayer piezo actuators with rapid rise times or high frequencies. Providing sink/source currents up to 10 amps and an output voltage swing of 160V-pp (-30V to +130V), the piezo driver delivers up to 1200 watts of peak power. A temperature sensor input provides overheating protection of piezo actuators.
Piezo actuators allow response times in the microsecond range. This behavior is beneficial for operating fast switches, valves, micromachining and micro-dispensing equipment, as well as for active optics and vibration cancellation applications. The E-619 high power piezo driver comes in two standard versions with a maximum bandwidth of 20kHz and 3kHz, respectively. Optional upgrade modules for closed-loop position servo control and digital control via a USB and TCP/IP interface are also available.
