Amplificateurs standalone

Pour répondre aux exigences de compacité en termes de conditions de pilotage et de contrôle de ses actionneurs piézo (statique, pulsé, dynamique), CEDRAT TECHNOLOGIES a développé 3 amplificateurs & contrôleurs autonomes: CAu10, CAu20, et CCBu20.

La nouvelle génération d’amplificateurs compacts CAuxx pour actionneurs piézo inclut des interfaces PCB avec des connecteurs standards ou des broches supplémentaires à souder sur votre PCB avec 2 lignes de connecteurs à pas 1.27mm.

La carte contrôleur compacte CCBu20 est un contrôleur tout-en-un embarqué qui peut piloter et contrôler jusqu’à 2 actionneurs piézo en boucle fermée.

Description

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.

Description

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.

Performance

Maximum output current: 5 mA

Available options

Push Pull
