Introduction
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.
A range of front panel controls provide maximum application flexibility, these include input signal
inversion, variable gain, DC offset, and variable voltage limits. A 9-pin DSUB connector on the front
panel includes signals for the input, voltage monitor, current monitor, shutdown monitor, and
shutdown command. A four-digit LCD screen also displays the DC voltage.
The output connectors include BNC, LEMO 00, LEMO 0B.302, and plug-in screw terminals. The PX200
is suited to a wide range of applications including electro-optics, ultrasonics, vibration control,
nanopositioning systems, and piezoelectric motors.
