To fulfill various requirements in terms of driving and control conditions for its piezo actuators (static, pulse, dynamic), the CEDRAT Group has developed 3 different families of standard drivers:
CA45 rack: Low cost & compact (1 channel) linear voltage amplifier for precise and quasi-static motion.
LA75 rack: Linear voltage amplifier for dynamic and precise motion.
SP75 rack: Switching power amplifier for fast motion.
These standard drivers can be equipped with controllers and sensor conditioners.
Miniature Amplifier CAµ10
