PDu150CL Low Noise 150V Piezo Driver with Strain Gauge Feedback



SKU: PDu150CL Category:


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.

Key features include:

  • Ultra-low Noise: 26uV (1uF Load, 0.03 Hz to 1 MHz)
  • Output Voltage -30 V to +150 V
  • Output Current: 100 mA per channel
  • Signal Bandwidth: 180 kHz
  • Power Bandwidth: 80 kHz (150 Vp-p)
  • Comprehensive overload protection
  • Dimensions: 76 x 40 x 37 mm (L x W x H)
  • Weight: 80 g
