E-650.00 is a bench-top piezo driver, especially designed for low-voltage, multilayer piezo bender actuators (bimorphs) such as the PL112 to PL140 (see link). It is equipped with a special circuit that can provide one fixed voltage and a variable voltage in the range of 0 to 60 V for differential piezo operation. The driver can output and sink a peak current of 300 mA. A 3 1/2 digit display shows the piezo voltage.
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-650.OE is the OEM version of the E-650.00. It provides peak output power of 8 W. The electronics are fully enclosed in a metal case. All inputs and outputs are via 8 header pins located on the bottom of the module. The E-650.OE is not intended for manual operation.
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.
