The E-462.00 piezo driver is a low-cost amplifier / driver for PICA™ high-voltage PZTs. It can output a peak current of 0.5 mA and is specially designed for static and quasi-static applications. Because the unit requires an operating current of only 80 mA @ 12 V, battery operation is possible.
Analog Control
E-462 amplifiers are designed to provide precise control of open-loop piezo positioning systems. The amplifier output voltage is determined by the analog signal at the Control Input combined with the DC-offset potentiometer setting.
PCB-Mount Version for OEMs
The E-462.OE version is fully enclosed in a metal case an designed for mounting on circuit boards. All input connections are via 6 header pins located on the bottom. The HV output is via a coaxial cable with LEMO connector. This OEM module does not provide manual controls. If dynamic (>1 Hz) PZT operation is required, please consider the E-464 (see link) (3-channel bench-top amplifier), E-470 (see link) or E-508 (see link) amplifiers (modular systems with sensor / servo option).
Computer Control
Optionally digital control via a 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(tm) technology providing enhanced system resolution.
