The PDu150CL combines a high-voltage power supply, precision strain conditioning circuit, feedback controller, and ultra-low noise amplifier (26uV RMS) into a package the size of a credit card. It provides all of the necessary functions for high-resolution open-loop or closed-loop control of piezoelectric actuators with or without integrated strain sensors. The PDu150CL produces up to 300mA of output current at frequencies up to 80 kHz and is protected against short-circuit, average current overload, and excessive temperature. The strain conditioning circuit utilizes a novel bridge driver and amplifier circuit to provide a closed-loop positioning resolution of 0.02% full-scale.
PDu150CL将高压电源，精密应变调节电路，反馈控制器和超低噪声放大器（26uV RMS）组合为信用卡大小的封装。 它为具有或不具有集成应变传感器的压电执行器的高分辨率开环或闭环控制提供了所有必要的功能。 PDu150CL可在高达80 kHz的频率下产生高达300mA的输出电流，并可防止短路，平均电流过载和温度过高。 应变调节电路采用新颖的桥式驱动器和放大器电路来提供0.02％满量程的闭环定位分辨率。
