The PDu150 is a complete miniaturized power supply and ultra-low noise driver for up to three 100V, 120V or 150V piezoelectric stack actuators. Output currents up to 100mA per channel are developed at frequencies up to 80 kHz with exceptionally low noise. The three channels can be connected in parallel to produce an output current of up to 300mA. The noise level of 26uV is typically an order of magnitude better than the best full-size instruments even though the output power is similar. With a peak-to-peak resolution exceeding one part-per-million or 20-bit, the PDu150 exceeds the most demanding requirements in semiconductor machinery, scanning probe microscopy, optics, vibration control, and nanopositioning.

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 44 mm (L x W x H)
  • Weight: 80 g

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
