1200W High Power Piezo Driver for Fast Switching Applications |
|
(Nanowerk News) Nano precision motion industry leader PI (Physik Instrumente) LP 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. | |
PI's new E-619 Modular High-power Piezo Amplifier for Dynamic Applications with Multilayer Actuators (shown with P-882 – P-888 PICMA® Stack Multilayer Piezo Actuators) | |
1200W Peak Power, 160Vpp Voltage Swing, 9.5” and 19” Racks for 1 to 3 Channels Piezo Driver Modules |
|
Providing sink/source currents up to 10 amps and an output voltage swing of 160V-pp (-30V to +130V), the new piezo driver delivers up to 1200 watts of peak power. Despite its high performance, this amplifier is very efficient due to its energy recovery circuitry. A temperature sensor input provides overheating protection of piezo actuators. | |
What are the Applications of High Power Piezo Amplifiers? |
|
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. | |

Options: 20kHz Bandwidth / 3kHz Bandwidth, Servo Controller, Computer Interface |
|
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. | |
