| New Control Unit for Piezoelectric Bender Actuators | 
 |
| Two new piezo bender actuator
controllers are now available. These devices have been specifically designed
to meet the needs of the PI multi-layer bender (see Fig. 20 for basic principle).
The bench top version, i.e., E-650.00, features a display, manual offset
adjustment, and sockets for the control signal, monitor and the piezo output
(Fig. 18).

Fig. 18: The E-650.00 control unit for piezoelectric bender actuators The E-650.OE compact model was specifically developed for OEM use. This model’s inputs and outputs are via 8 soldering pins (Fig. 19). The peak output power is 18 W for the E-6500.00 and 8 W for the E-650.0E and the output voltage for both devices is between 0 and 60 V
