Micropositioning Made Simple With SmarAct’s Controller

The CU-3C controller is a single board version of the HCU-3C controller. It has no manual control elements, no display and comes with or without housing. This makes it an ideal product for original equipment manufacturers (OEM), wanting to integrate the CU-3C controller into their products. As with the HCU-3C controller, a PC can be connected to the CU-3C controller via its USB or RS232 interface.

By choosing the optional sensor support, the CU-3C enables you to control closed-loop positioners with integrated microsensor.

The CU-3C controller provice an USB interface for connection to a PC. SmarAct’s stand-alone graphical user interface for controlling the connected positioners or you can develop your own software application by using SmarAct’s Dynamic Link Library or LabVIEW® driver.
