0.3. Warnings and Safety Notes
Warning: High Voltage
The PZT driver described in this document is power amplifier
that outputs high voltages which can generate lethal currents.
We strictly advice you to not open the chassis when line voltage
is connected. When using PZT translators with bare contacts,
never touch the conductors. Even if the PZT is not connected to
the driver, the ceramic may be charged up to high voltage!
Be aware of the risk of injury if not following general accident
prevention regulations!
1. Introduction
E-663 is a bench-top amplifier for driving three low-voltage piezoelectric translators
(LVPZTs). It offers three independent output channels capable of outputting and
sinking a peak current of 140 mA and an average current of 60 mA each.
The output voltage range covers -20 to +120 Volts that can be controlled manually
via front panel potentiometers or by analog control signals.
Three 3½-digit LEDs display the output voltage.
E-663 LVPZT amplifiers can be used for static and dynamic applications. The
excellent output stability and linearity allow the device to be used with high-
resolution positioning systems.
E-663.00 features:
•3 x 14 W Peak Power
•3 independent channels
•3 x 3½-Digit Displays

2. E-663 General Description
E-663 PZT drivers have three individual amplifier channels to drive three LVPZTs.
Each channel is equipped with a 10-turn potentiometer for manual control of the
output voltage (DC-offset setting).
External analog control signals can be connected to the BNC sockets on the front
panel.
The current output voltages are shown on a 3½-digit LED displays.
2.1. Operating and Display Elements :
(1) Three 3½ -digit LED Display
(2) Three LEMO output sockets
(3) Three BNC input sockets
(4) Three DC-Level potentiometers
(6) Line switch/fuse assembly on the rear panel

2.2. Line Power and Fuses
The power connection, input voltage selection and line
fuses are located on the rear panel. Unless you
request a specific setting, the unit will be set up for the
line voltage we believe predominant in your country.
New Fuses Required when Changing
Supply Voltage
To connect the product to a different supply voltage, it
is necessary not only to reorient the fuse carrier so that
the desired voltage is visible in the window, but also to
replace both the line fuses with the value appropriate
for the new voltage. Lower supply voltage requires
higher current.
To access the fuse carrier, remove the power cord,
and pry open the door that covers the carrier. The
carrier can then be pried out, exposing the two line
fuses (see illustration at right).
After replacing the fuses, reinstall the carrier in the new
orientation; check that the correct voltage setting is
visible through the window in the door when it is
reclosed.
Voltage Setting & Fuse Values:
115 V: 1.6 A*
230 V: 0.8 A*
* slow blow fuses required

3. Modes of Operation
E-663 LVPZT Amplifiers can be operated in 2 ways:
1. Manual, static operation:
The output voltage for each channel is set by a 10-turn potentiometer (DC-Offset)
in the range of 0 to +100 Volts.
2. External, static and dynamic operation:
The output voltage for each channel is controlled by analog signals ranging from -2
to +12 V applied to the BNC inputs, ranging. Multiplying by the gain factor of 10, an
output voltage of -20 to +120 V results. In this mode, the DC-offset potentiometer
allows for continuous shifting of the input voltage range between -2 to +12 V.
4. Starting Operation
Warning: High Voltage
The PZT driver described in this document is power amplifier
that outputs high voltages which can generate lethal currents.
We strictly advice you to not open the chassis when line voltage
is connected. When using PZT translators with bare contacts,
never touch the conductors. Even if the PZT is not connected to
the driver, the ceramic may be charged up to high voltage!
Be aware of the risk of injury if not following general accident
prevention regulations!
Before you power up the E-663, check whether the AC operating voltage is set to
the right value (verify the specified line voltage at the rear panel).
Check basic operation of the E-663 functions without any PZT translators
connected. Select any of the channels and set the corresponding DC offset
potentiometer. The value read from the display represents the actual output
voltage. Turning the potentiometer from one end to the other should cause the
voltage reading to range from 0 to +100 Volts.
Turn the DC-OFFSET potentiometers counterclockwise (CCW) to zero the output
before you connect PZT translators to the LEMO output sockets. Otherwise the
translator may expand abruptly and connected parts could be damaged.
After the device is powered on, the displacements of the PZTs can be controlled
by using the DC OFFSET potentiometers, either exclusively or in conjunction with
the analog input signals.
