he 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)组合成一个信用卡大小的包。它提供了高分辨率开环或无集成应变传感器的压电致动器闭环控制的所有必要功能。PDu150CL产生高达300mA的输出电流，频率高达80 kHz，并能防止短路、平均电流过载和温度过高。应变调理电路采用了一种新型的桥驱动电路和放大器电路，实现了0.02%的全尺寸闭环定位分辨率。
