PiezoDrive - Model PDu150CL -Low Noise 150V Piezo Driver with Strain Gauge Feedback
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 resistive strain sensors. The PDu150CL develops up to 300mA of output current at frequencies up to 80 kHz with very low noise. It is suited to demanding applications such as semiconductor machinery, scanning probe microscopy, optics, vibration control, and nanopositioning. The PDu150CL can be purchased as a calibrated pair with an SCL Series Closed-Loop Stack Actuator.
The PDu150CL is protected against short-circuit, average current overload, and excessive temperature. Passive cooling is available for low power applications or the integrated fan can be used when power dissipation is above 5W. The PDu150CL can be mounted with four M2.5 screws or directly to a host motherboard (PDu150CL-PCB).
