To fulfill compactness requirements in terms of driving and control conditions for its piezo actuators (static, pulse, dynamic), CEDRAT TECHNOLOGIES has developed 3 standalone amplifiers & controllers : CAu10, CAu20, and CCBu20.
The new generation of compact amplifiers CAuxx for piezo actuators includes PCB interfaces with standard connectors.
The Compact Controller Board CCBu20 is an embedded all-in-one controller for the driving & close loop control of up to 2 piezo actuators.
The Graphical User Interface to modify the parameters of the CCBu20 is similar to the UC digital controllers that can be downloaded on the dedicated page.
The Compact Controller Board CCBu20 is an embedded all-in-one controller for piezo actuators. It features everything to drive and control a 2 axis piezo-mechanism in position loop. In standard, its integrated dual channel SG conditioner allows reading the position of the two axis of the mechanism. A powerful processor realizes closed-loop control at high refresh rate, and the controller can be tuned by the user with the HDPM45 interface. Thanks to a compact design, it has dimensions of only 91x77x37mm, making it suitable for embedded applications, or industrial applications where the volume is an issue. The Graphical User Interface to modify the parameters of the CCBu20 is similar to the UC digital controllers that can be downloaded on the dedicated page.
Supply voltage of +12Vdc to +28Vdc; analog or digital commands with RS422 protocol, up to 2 axis in push pull; Piezo voltage: -20V to +150V; Max. current (sinus): 33mA; Max current (pic): 200mA.
0-5V analog sensor input, Advanced controller
The CAu10 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.
Maximum output current: 5 mA
The CAu20 is an extra-miniature single channel amplifier for piezo actuators in open loop, whis is able to deliver 100mA and requires a DC voltage of 12 to 24 V.
Continuous max current: 100 mA
