The E-660.00 piezo driver is a low-cost amplifier for low-voltage piezo actuators and positioning stages. It can output and sink a peak current of 20 mA and an average current of 10 mA. The E-660 is designed for static and low-level dynamics applications. The low operating current of only 150 mA @ 12 V makes the unit suitable for battery operation.
Voltage-Controlled Piezo Operation
This precision piezo driver is designed for voltage-controlled piezo operation in both dynamic and static mode. Its output voltage is determined by the analog control signal at the BNC Control Input socket, optionally combined with the DC-offset potentiometer. Voltage-controlled operation (in contrast to position-controlled operation) is used in applications where the fastest possible response and very high resolution with maximum bandwidth are essential, and/or when commanding and reading the target position in absolute values is either not important or accomplished with external position feedback.
The precision 10-turn potentiometer can also be used alone to set the output voltage manually.
Compact OEM Version
The E-462.OE version is fully enclosed in a metal case and designed for mounting on circuit boards. All inputs and outputs are via 8 header pins located on the bottom of the module. This OEM module does not provide manual controls.
Remote Control via Computer Interface
Optionally, digital control via an external D/A converter is possible. For several D/A boards from National Instruments, PI offers a corresponding LabVIEW driver set which is compatible with the PI General Command Set (GCS), the command set used by all PI controllers. A further option includes the patented HyperBit™ technology providing enhanced system resolution.
