Controller for piezo system DSM
CE ; RoHS ; 90 - 500 mA ; 200 V

DSM's linear piezo amplifiers, piezo drivers, and piezo controllers are high-power units used for open-loop and closed-loop servo control of piezo actuators and piezoelectric stage systems in precision motion control and positioning applications. DSM's amplifiers and controllers are typically sold in single-channel benchtop models, but multi-channel and OEM styles are also available.

DSM's VF series of linear piezo amplifiers are voltage followers that amplifiy a low voltage analog input signal. The VF-500 amplifier provides 500 mA of continuous current (1A peak current) for piezo material rated up to 200 V. The benchtop model features an optional LCD menu-driven display and built-in function generator for sinusoidal output motion of an attached piezo device.

DSM's new OEM VF-90 module is compatible with National Instrument's CompactRIO and CompactDAQ platforms and is CE rated and RoHS compliant. The VF-90 provides 90mA of continuous current for voltage ranges up to 200V.

The SA series of servo amplifiers includes the functionality of the VF series and adds additional capabilities for communication, I/O, and stand-alone servo control of piezo devices. DSM has integrated the SA controller with feedback from a capacitive displacement sensor to achieve nanometer-level resolution in piezoelectric positioning systems. Communication with the SA servo amplifier is done through RS-232, and LabView *.vi files are available for control of the SA functions.
