Newport ESA-CXA 3-Axis Electrostrictive Actuator Controller
Model ESA-CXA provides precise adjustability of one to three AD actuators, for manual or low-bandwidth external control. Three analog input ports allow control via a computer with a D/A board. A bright red LED display shows the applied voltage for a selected actuator and can easily be read from across a room. High-stability DC power supplies provide better than 15mV RMS ripple and 1% voltage stability over eight hours.
