E-471:00 Configuration example: E-471.00 HVPZT Piezo Amplifier,
with optinal E-509.S1 Piezo Servo Controller (strain gages) and E-515.i1
16 bit DAC Interface/Display.E-470 Series High Power Amplifiers/ Controllers are specifically designed to drive high capacitance Piezo actuators. They are based on the E-420 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). Four versions are available:
1) E-470.00 bench-top amplifier for open loop Piezo actuators
2) E-471.00 19" rack mount amplifier offering optional servo control, interface and display
3) E-472.00 19" rack mount two channel amplifier
4) E-420.00 OEM amplifier module with integrated AC power supply
All versions can be operated in two ways.
- Manual, static operation
The output voltage can be set by
a 10-turn, DC offset potentiometer in the range of -3 to -1000 Volts- External operation
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 allows for a continuous variation of the input voltage range between 0 V to +10 V and -10 V to 0 V (click here).For frequency response with selected HVPZTs
