Piezo actuators and positioning systems require unique drive and control electronics. DSM's electronics expertise and products keep pace with their mechanical counterparts. The electronic products include a family of linear piezo amplifiers and piezo drivers. DSM also offers custom circuit design services for piezo-based applications.
DSM's linear piezo amplifiers provide open-loop driving signals or closed-loop servo control of piezoelectric positioning systems. Our piezo amplifiers are typically sold as single channel benchtop or OEM instruments; custom multi-channel styles are also available.
OPEN-LOOP PIEZO ELECTRONICS
Voltage Follower (VF) Series
DSM's VF linear piezo amplifiers are high-quality voltage followers that amplify a low voltage input signal.
CLOSED-LOOP PIEZO ELECTRONICS
Servo Amplifier (SA) Series
The SA-500 servo amplifier includes the functionality of the VF-500 and adds additional capabilities for communication, I/O, and stand-alone servo control of piezo positioning systems. The SA-500 is typically sold as part of a custom system using a customer's specified feedback device. High-resolution position control can be achieved using the SA amplifier to close the loop on an analog or digital feedback signal integrated into the positioning system.
