PI (Physik Instrumente) has released the new model E-619, a high-power piezo amplifier designed to drive high-capacitance multilayer piezo actuators with rapid rise times or high frequencies. As a special form of electro-ceramics, piezo materials are the gold standard when it comes to speed, force, and precision in a small package.
Providing sink/source currents up to 10 A and an output voltage swing of 160 V-pp (-30 V to +130 V), the new piezo driver delivers up to 1,200 W of peak power. Despite its high performance, the amplifier is efficient due to its energy recovery circuitry. 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 20 kHz and 3 kHz, respectively. Optional upgrade modules for closed-loop position servo control and digital control via a USB and TCP/IP interface are also available.
PI has in-house engineered solutions with over 4 decades of experience working with customers to provide products that meet application demands, and can quickly modify existing product designs or provide a fully customized OEM part to fit the exact requirements of the application.
