The E-470 series high-power amplifier/controllers are specifically designed to drive high-capacitance PZT actuators. They are based on the E-420 4-quadrant amplifier module, which can output and sink a peak current of 500 mA and an average current of 100 mA in a voltage range of -3 to -1100 V (positive or bipolar range, jumper selectable). OEM, 19“ rackmount, bench-top, and two-channel versions are available, some with servo-control module and display (see Ordering Information for standard combinations).
Standard versions can be operated in two ways:
I. Manual Control:
The output voltage can be set by a 10-turn, DC-offset potentiometer in the range of -3 to -1000 Volts
II. External Control:
Output voltage is controlled by an analog signal applied to the BNC input, ranging from 0 to 11 Volts. Multiplying by the gain factor of -100, an output voltage range of -3 to -1100 Volts results. The DC-offset potentiometer adds a DC bias to the input, allowing continuous shifting of the input range between 0 V to +10 V and -10 V to 0 V (see page see link).
See graph for frequency response with selected HVPZTs.
Upgrades
The E-471.00 version allows installation several upgrade options for enhanced versatility (see Ordering Information).
Two additional modes are possible with versions having the
E-509 Sensor & Servo-Controller Module upgrade:
I. Manual Closed-Loop Operation
Displacement of the PZTs can be set by a 10-turn DC-offset potentiometer in the range of zero to nominal displacement.
II. External Closed-Loop Operation
Displacement of the PZT is controlled by an analog signal in the range of 0 to +10 V, applied to the BNC input. The controller is calibrated in such a way that 10 V corresponds to maximum nominal displacement and 0 V corresponds to 0 displacement. The DC-offset potentiometer can be used to add an offset voltage of 0 to 10 V to the input signal.
