Parallel Pre-Stressed Actuators (PPA)

Super Technologies offers a range of Parallel Pre-Stressed Actuators (PPA) from Cedrat Technologies, France. PPAs are solid-state linear actuators. They only use the expansion of the active material, in 33-mode, to produce a useful displacement. This displacement is proportional to the voltage within a 170 V range. Typically, the actuator's deformation is about 0.1% (1 µm/mm), so their displacements are limited to about 100 µm. However, the forces are naturally high, easily higher than 1 kN. Parallel pre-stressed actuators use an external deformable frame to pre-stress the ceramics. The level of pre-stress can be higher. PPAs are cheaper, more compact and display a much better dynamic behaviour than conventional direct piezo actuators. Super Technologies is a leading system integration and product distribution organisation, engaged in providing cutting edge technology solutions. It carries a clear vision of providing the best in the world to engineers in mechanical and electronics development in its technical experience with a good team.
