Safety Precautions
1Safety Precautions
WARNING
Failure to heed warnings in this manual can result in bodily
injury or material damage. Note that E-650
Controller/Amplifier do not contain any user-serviceable
parts.
!
CAUTION
The E-650.OE Amplifier PCB is an ESD-sensitive
(electrostatic discharge sensitive) device. Observe all
precautions against static charge buildup before handling
these device.
Avoid touching circuit components, pins and PCB traces.
Discharge any static charge you may have on your body by
briefly touching a conductive, grounded object before you
touch any electronic assembly. Pose PCBs only on
conductive surfaces, such as ESD-safe transport
containers (envelopes, foam). Electronic subassemblies
must always be kept and transported/shipped in conductive
packaging.
Make sure that no conductive particles of any kind (metallic
dust or shavings, broken pencil leads, loose screws)
contact the device circuitry.
DANGER
E-650s are amplifiers generating high voltages of up to
60 V for driving piezo actuators. The output power may
cause serious injuries.
Working with these devices or using piezoelectric products
from other manufacturers we strictly advise you to follow
the General Accident Prevention Regulations.
All work done with and on the devices described here
requires adequate knowledge of handling high voltages.

Safety Precautions
! CAUTION
Handle bender actuators (ceramic elements!) with care! Do
not drop a bender actuator; avoid subjecting it to any kind
of mechanical shock.

Introduction
2Introduction
E-650.00 is a bench top amplifier especially designed for Low
Voltage PICMA®multilayer bender actuators from PI
("Bimorphs"; see PI catalog) such as the PL-122 to PL-140. It
contains one amplifier that can output and sink a peak current
of 300 mA.
An OEM version is also available (E-650.OE, see p. 10).
Features:
Specially Designed to Drive Multilayer "Bimorph"
Actuators
18 W Peak Power
LCD Voltage Display
Output Voltage Range 0 to 60 V + One Fixed Voltage for
Full Differential-Voltage Control
The PICMA®actuators require full differential-voltage control
with constant voltages of 0 V and +60 V and a variable voltage
from 0 V to +60 V (see Fig. 1). Note that a control input voltage
of 0 V corresponds to a PZT variable output of about +30 V,
which puts the actuator in the middle position (i.e. deflection ≈
0 µm).

! CAUTION
Handle bender actuators (ceramic elements!) with care! Do

4.1 Operating Requirements
A power supply for 2A @ 15 VDC is required.
Recommended is the use of the 650.PS power supply.
4.2 Operating Modes
External operation:
Output voltage is controlled by an analog signal applied to the
BNC input, ranging from 0 to 10 V. Multiplying by the gain factor
of 6, an output voltage range of 0 to 60 V results. The DC offset
potentiometer can be used to bias the control input voltage. The
control voltage is applied to the input socket (BNC connector)
"Control Input", Input range: 0 ...+10 V.
Manual Operation:
Output voltage can be set by a 10-turn, DC offset potentiometer
in the range of 0 to 60 V.

5.2 Pin Assignment
"PZT Output" connector
Fig. 3: Pin Assignment
Pin 1 is internally connected to pin 2 and pin 4 is internally
connected to pin 5, so that the appropriate output voltages are
present on both pins of such a "pair" in parallel. It is also
possible to connect two bender actuators (sharing the same
connector), but they can not be commanded separately.
