The Physik Instrumente E-662 LVPZT Amplifier and Position Servo-Controller is a bench-top, amplifier/position servo controller with integrated RS-232 computer interface and 12 bit D/A converter for Low Voltage PZTs. The amplifier can output and sink a peak current of 360 mA and an average current of 120 mA. The position servo controller works with either strain gauge sensors (E-662.SR) or LVDT sensors (E-662.LR).
Can be operated in 6 ways:
- Open loop (amplifier mode)
1. Manual operation: Output voltage can be set by a 10-turn, DC offset potentiometer in the range of 0 to 100.
2. External operation: Output voltage is controlled by an analog signal applied to the BNC input ranging from -2 to +12 V. Multiplying by the gain factor of 10, an output voltage range of -20 to +120 V results.
3. Computer Control (toggle switch selected): Output voltage is controlled via the RS-232 computer interface in the range of 0 to 100 V with a resolution of 12 bits. The DC offset potentiometer and BNC analog input are inactive when in computer control mode.
- Closed loop (position control mode)
1. Manual operation: Displacement of the PZTs can be set by a 10-turn, DC offset potentiometer in the range of zero to nominal displacement.
2. External operation: Displacement of the Piezo 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 with maximum nominal displacement and 0 V corresponds with 0 displacement.
3. Computer Control (toggle switch selected): Displacement of the Piezo is controlled via the RS-232 computer interface in the range of 0 to maximum nominal displacement, with a resolution of 12 bits. The DC offset potentiometer and BNC analog input are inactive when in computer control mode.
