E-651 • E-614 Piezo Amplifier / Servo Controller

For Closed-Loop Multilayer Bending Actuators

For closed-loop multilayer piezo bending actuators
Benchtop and OEM board versions
One- and two-channel versions
Position control for strain gauge sensors
Overheat protection

The E-651 is a benchtop device, especially designed for P-871 multilayer bending actuators equipped with strain gauge sensors. One- and two-channel versions are available. The compact E-614.2BS OEM board provides the same functionality as the 2-channel model.

The control signal specifies the piezo position in the servo loop. The servo controller is set so that maximum displacement is achieved at an input control voltage of +/- 5 V. The E-651 can also be operated as a pure voltage amplifier. The analog input signal in a range of -5 to +5 V then controls the output voltage ranging up to 60 V.
