The PDm200 is a high-performance power supply and linear amplifier module for driving piezoelectric actuators. The output voltage range can be switched between bipolar or unipolar modes with a range of 100V, 150V, or 200V. Up to ±400V can be achieved in the bridged configuration. In the unipolar mode, the negative output range is fixed at -30V for use with stack actuators. The PDm200 can drive stack actuators; standard piezoelectric actuators; two wire benders; and three-wire piezoelectric benders requiring a bias voltage.
