## Function

Three-channel high-voltage piezoelectric actuator controller providing independent closed-loop or open-loop control for nanometer-precision positioning applications. Generates 0-150V output per channel with sub-millivolt resolution, supporting capacitive loads up to 2µF. Interfaces via analog BNC inputs (0-10V), manual front-panel controls, and optional computer control through RS-232/USB communication. Integrated noise filtering, adjustable PID parameters, and position feedback monitoring enable stable operation of piezo-driven stages, mirrors, and positioners. Commonly used in optical alignment, microscopy, interferometry, and precision manufacturing requiring multi-axis nanoscale motion control.
