ORDERING INFORMATION

PRICE
Piezo Systems offers a single channel high frequency ampli-
fier for driving a variety of piezo actuators, including
stacks,bimorphs,and single sheets.
The ability of an amplifier to drive a piezo device statical-
ly is determined primarily by the voltage level and stabili-
ty. Its ability to drive a piezo device dynamically is deter-
mined by the capacitance of the actuator, the voltage to
which it must be charged,and the number of times it must
be charged and discharged per second.These establish the
current,voltage,and frequency requirements of the ampli-
fier.
The EPA-102 is a high voltage (± 200 Vp),high current (±
200 mA), and high frequency (DC to 300 KHz) amplifier
designed to drive higher capacitive (low impedance) loads,
such as low voltage stacks, at moderate frequencies or
lower capacitive loads, such as ultrasonic devices, at high
frequencies.
Low Electrical Noise, Low Distortion: The amplifier is
made with a high quality Apex High Voltage Hybrid
Operational Amplifier, and utilizes high regulation linear
power supplies.They are housed in a heavy high conduc-
tivity aluminum case which provides an excellent shield
from external electromagnetic interference.
Input and Output Protection: Piezo loads present special
problems to electronic drivers. The EPA-102 provides
heavy input and output protection to take care of all
shorting, turn-on, turn-off, and load generated voltage
occurrences which can damage either the amp or your
actuator.
Manual Bias Controls (Polarity and DC offset): Useful for
making manual adjustments of drive voltage to verify piezo
actuator static motion, for static setting, or for applying
DC bias to dynamically driven piezo actuators such as
piezo stacks.
External Control (via analog signal to the BNC input con-
nector): Accepts up to ± 10 Vp signal waveforms from
external signal generators,computer controllers,or feed-
back networks from DC to rated frequency. The com-
bined AC plus DC offset voltage is adjustable from zero to
the maximum rated voltage.
