CEDRAT Drivers and Controllers for Piezo Actuators

CEDRAT Piezoelectric Drivers

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. 

CAu10-imag_small

Miniature Amplifier CAµ10

The CAµ10 is a unipolar (5V..150V) miniature linear amplifier with low noise and low cost features. A SPI digital to analogue converter is able to convert 12 bits words in analogue signal for the linear amplifier. Optional inputs can be connected if necessary to shunt the SPI bus and send directly the analogue order on the linear amplifiers. The CAµ10 is compatible with the numeric controller UC45.

Maximum output current: 5 mA

Options: Push Pull

Status: Standard Product
