Introduction
1.1
Overview
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.
Analog Control
E-462 amplifiers are designed to provide precise control of open-loop piezo
positioning systems. The amplifier output voltage is determined by an
analog control signal.
PCB-Mount Version for OEMs
The E-462.OE1 version is fully enclosed in a metal case and designed for
mounting on circuit boards. All input connections are via 6 header pins
located on the bottom. The PZT (piezo) high voltage output is via a coaxial
cable with LEMO connector.
If dynamic (>1 Hz) PZT operation is required, please consider instead the
E-464 (3-channel bench-top amplifier), E-470 or E-508 amplifiers (modular
systems with sensor/servo option).
1.2
Prescribed Use
Based on their design and realization, E-462 Piezo Amplifiers are intended
to drive capacitive loads, in the present case, piezoceramic actuators.
E-462s must not be used for applications other than stated in this manual,
especially not for driving ohmic (resistive) or inductive loads.
