Product Description

The PA25 is a single channel amplifier suitable for driving low voltage (150V) piezo actuators. The PA25 amplifier combines low noise and outstanding stability with high power output, making it ideal for open loop, high resolution control of piezos. The PA25 is equipped with a front panel analog input BNC for high precision command voltage control. A single channel high voltage (0 to 150V) output is conveniently located on the front panel. This high voltage BNC connector can be interfaced to our bare piezoactuators for precision motion applications.
