DSM’s VF-500 linear piezo amplifier is a high-quality voltage follower that amplifies a low voltage input signal. High-power benchtop instrument providing 500 mA maximum continuous current (1 A peak) for driving piezoelectric devices rated up to 200V.

DSM's VF-90 linear piezoelectric amplifier module provides functionality for driving piezoelectric (capacitive) loads in an extremely compact form factor. Compact original equipment manufacturer (OEM) format providing 90 mA maximum continuous and peak current for piezo devices rated for up to 150 V, 200 V, or for piezo benders (bimorphs) rated for up to ± 100 V. Low noise for precision applications; 0.5 mVrms typical. The VF-90 features over-current, over-temperature, and short-circuit protection as well as protection against over/under voltage conditions on the power line.

The SA-500 servo amplifier includes the functionality of the VF-500 plus adds additional capabilities for communication, I/O, and stand-alone servo control of piezo positioning systems. 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.

The MD-90 is a 2-channel linear amplifier for operating the I-20 piezo motor. This original equipment manufacturer (OEM) unit can be used in two primary ways as a: 1.) 2-channel piezo motor driver complete with quadrature encoder feedback and 2.) 2-channel piezo device amplifier with analog feedback for both closed and open loop operation.

The UMD3.1 is a 3-channel motor driver designed to work with the SUM-40NM nonmagnetic motor. This driver can provide power to 1, 2, or 3 SUM-40NM motors, and is designed to locate the electronics away from the magnetic field. Connection and operation is made easy with a USB cable and ASCII commands.
