PI Announces High-Performance Piezo Actuators And High-Voltage Amplifiers

Successful high-force piezo actuator series updated with Power PZT ceramics; new line of high-voltage drivers also available

PI is the leading manufacturer of piezo actuators and offers the largest product variety in terms of load capacity, travel range, temperature range and dynamics. While most medium and low force actuator applications are covered by patented PICMA® multilayer technology, the classical technology enables applications where extremely high forces are required or high levels of customization are needed.

Lower Power Consumption, Forces to 30,000 N, Amplifier Power from 1 to 2000 W
Four newly developed, preloaded HVPZT actuator series (P-212, P-216, P-225 and P-235) are now equipped with the advanced PIC 255 PICA Power piezoceramic stacks. They feature load capacities from 2,000 N to 30,000 N, travel ranges from 15 µm up to 180 µm and standardized dimensions. The integrated preload makes these actuators ideal for dynamic applications (e.g. precision machining, active vibration damping, etc.) and push-pull applications. In contrast to HVPZT actuators of older design, they have positive polarity and a different connector. The low-capacitance, piezo ceramics require less electric power – a special advantage for high dynamics applications. Five RoHS compliant high-voltage amplifiers ranging from 1 to 2000 watts of power are available to drive the new HVPZT actuators. All models (E-462, E-464, E-508, E-421 / E-470 / E-471 / E-472, E-481) are delivered preset to provide positive output voltages and otherwise improved in many details compared to their predecessors.
