Introduction; Warnings / Notes - PiezoDrive PD32 Manual

Introduction

The PD32 is a high‐bandwidth, low‐noise linear amplifier for driving up to 32 piezoelectric actuators. The
voltage range is configurable from +50V to +/‐140V and includes asymmetric voltage ranges such as ‐20V
to +120V. The PD32 works seamlessly with common multi‐channel DAC cards and provides exceptional
ease of use and compatibility with programming tools such as LabView and Simulink. The compact size and
19‐inch rack compatibility provides a comprehensive off‐the‐shelf solution for driving hundreds or
thousands of piezoelectric actuators.
The PD32 is designed for demanding applications such as Adaptive Optics, Acoustic Beam Forming,
Materials Testing, Astronomy, Ultrasonics, and Vibration Control. With an output current of 150mA per
channel, a large array of piezoelectric actuators can be driven simultaneously at high frequencies. Positive
and negative high‐voltage bias outputs are also included for compatibility with piezoelectric bender
actuators.
Each channel is individually protected against short circuit and thermal overload. Status indicators on the
front panel provide individual monitoring of all channels. A digital status signal and external shutdown
command is also accessible from the input connector to allow remote monitoring and control. The input
and output connectors are industry standard 37 Pin D‐Sub connectors which are straight‐forward to
assemble. Adaptors are available for industry standard 32 Channel DAC cards.
