Stack Actuators 100V, 120V, 150V, 200V Plates and Tubes up to 100V Two Wire Benders up to 100V 0 to 200V with 200V bias Three Wire Benders 100V with 100V bias The PD200 is highly user configurable with jumpers for options such as the voltage range, polarity, and gain control. Two potentiometers are also provided to limit the positive and negative voltages to any arbitrary value between zero and full range. Due to the extensive configuration options, the PD200 is suited to a wide range of applications including electro‐optics, ultrasound, vibration control, nanopositioning systems, and piezoelectric motors. There are four output connectors including Lemo 00, Lemo 0B, BNC, and screw terminals that allow the direct connection to almost any commercially available piezoelectric actuator, including those from PI, Piezomechanic, PiezoSystems, etc. Warnings / Notes This device produces hazardous potentials and should be used by suitably qualified personnel under the supervision of an observer with appropriate first‐aid training. Do not operate the device when there are exposed conductors. High-Voltage... -

Page 5: Output Voltage Range
Output Voltage Range The output voltage range can be configured by disconnecting the amplifier from mains power then removing the top panel. The following voltage ranges can be obtained with the correct combination of installed jumpers. Note that incorrect jumper settings may destroy the amplifier. The standard output voltage range is 0V to 200V. However, the amplifier can be supplied with any voltage range by appending the order code with the voltage range code, for example, the standard configuration is PD200‐V200. The voltage range jumper locations are labelled with the LP, LG, and LN prefixes on the PCB. Voltage Range Code LP LG LN LK10 and LK12 0V to +200 ‐V200 LP1 LG3 Position A 0V to +150 ‐V150 LP2 LG3 Position A 0V to +100 ‐V100 LP2 LG2 Position A 0V to +50 ‐V50 LP2 LG1 Position A ... -
Page 6: Power Bandwidth
Figure 1. Maximum pulse time versus current Power Bandwidth With a capacitive load, the peak load current for a sine‐wave is where is the peak‐to‐peak output voltage, is the load capacitance and is the frequency. Given a peak current limit , the maximum frequency is therefore . However, the PX200 is protected by both peak and average current limits. The average current is defined as the average positive or negative current. For example, for a sine‐wave Therefore, for a sine‐wave / . Since the average current limit of the PD200 is fixed at 0.26 A, the maximum frequency sine‐wave, or power bandwidth of the PX200, is equal to 0.26 . The above result is true for any periodic waveform such as triangular signals. The RMS current for a sine‐wave can also be related to the average current, √ 2 The power bandwidths for a range of load capacitance values are listed below. ... - Page 7 Load Peak to Peak Voltage Cap. 200 150 100 50 No Load 230 kHz 310 kHz 470 kHz 520 kHz 10 nF 130 kHz 173 kHz 260 kHz 520 kHz 30 nF 43 kHz 58 kHz 87 kHz 173 kHz 100 nF 13 kHz 17 kHz 26 kHz 52 kHz 300 nF 4.3 kHz 5.8 kHz 8.7 kHz 17 kHz 1 uF 1.3 kHz 1.7 kHz 2.6 kHz 5.2 kHz 3 uF 430 Hz 570 Hz 870 Hz ...

Page 9: Noise
Noise The output noise contains a low frequency component (0.03 Hz to 20 Hz) that is independent of the load capacitance; and a high frequency component (20 Hz to 1 MHz) that is inversely related to the load capacitance. Many manufacturers quote only the AC noise measured by a multimeter (20 Hz to 100 kHz) which is usually a gross underestimate. The noise is measured with an SR560 low‐noise amplifier (Gain = 1000), oscilloscope, and Agilent 34461A Voltmeter. The low‐frequency noise is plotted in Figure 5. The RMS value is 650 uV with a peak‐to‐peak voltage of 4.3 mV. The noise level is approximately equal to the least significant bit of a 16‐bit digital‐to‐analog converter. t (s) Figure 5. Low frequency noise from 0.03 Hz to 20 Hz. The RMS value is 650 uV, or 4.3 mVp-p. The high frequency noise (20 Hz to 1 MHz) is listed in the table below versus load capacitance. The total noise from 0.03 Hz to 1 MHz is found by summing the RMS values, that is . Load Cap. Bandwidth HF Noise RMS ... -
Page 10: Input And Offset Configuration
Input and Offset Configuration The input stage is normally non‐inverting; however, it can be configured as inverting by changing LK14 and LK15 to their “B” position. The default jumper position is “A” which is marked with a white bar on PCB overlay. The amplifier can be supplied with an inverting input by appending the order code with –INV. Input Configuration Code Link Positions Non‐inverting (default) LK14 and LK15 Both “A” Inverting ‐INV LK14 and LK15 Both “B” Table 5. Input polarity configuration The input offset source is also configurable. When LK21 is in the “B” position, the offset is derived from the on‐board trim‐pot R15, which is adjustable from zero to full‐scale. The default configuration for LK21 is in the “A” position where the offset voltage is derived from the front‐panel potentiometer. The standard offset voltage range is from zero volts to full‐scale; however, for applications that require negative offset voltages, LK13 can be moved from the “A” to “B” position. In the “B” position, the offset range is from ‐100V to full‐scale. Offset Configuration Code Link Positions 0V to +200V Range (def.)
