PX200 Power Amplifier The PX200 is a low-noise high-current linear amplifier for driving piezoelectric actuators and other loads. The output voltage range can be unipolar, bipolar, or asymmetric from 50V to 200V. Refer to the specifications table for the available output voltage ranges. Two amplifiers can be connected in bridge-mode to provide up to +/-200V or +400V. The PX200 has a high output current up to 13 Amps peak and is well suited to precision applications that require high power and frequency. The PX200 can drive any load impedance including unlimited capacitive loads such as stack actuators; standard piezoelectric actuators; two wire benders; and three-wire piezoelectric benders requiring a bias voltage. Bias voltages can be generated using two auxiliary outputs linked to the power supply voltages.
