The Newport ESA-CXA is a three-axis precision motion controller designed to drive Newport AD Series and UDrive series electrostrictive actuators. It provides independent voltage control across X, Y, and Z axes with real-time digital monitoring, making it suitable for multi-axis positioning tasks in automation, research, and manufacturing environments. The controller combines manual potentiometer adjustment with external analog control capability, offering stable, low-ripple output across all channels.
