Page 3: Introduction
Two amplifiers can be connected in bridge-mode to provide up to +/-200V or +400V. The PX200 has a high output current up to 13 Amps peak and is well suited to precision applications that require high power and frequency. -
Page 4: Output Voltage Ranges
The output voltage range is specified when ordering. The standard voltage ranges and associated current limits are listed below. Since the PX200 has front panel controls for reducing the positive and negative output voltage range, choose a range equal to or slightly greater than required. -

5 Power Bandwidth Launch Online Power Bandwidth Calculator The online power bandwidth calculator estimates the highest achievable frequency with a capacitive load impedance. The calculator considers the current limit, slew-rate, output impedance, and small- signal bandwidth. PX200 V5 Manual 13/05/2022... - Page 6 Table 2. Maximum frequency (Hz) versus load capacitance and output voltage span In the above table, the frequencies limited by slew-rate are marked with an asterisk.

Page 7: Pulse Current Option
The maximum pulse duration versus peak current is described in Figure 1. The pulse current option can be ordered by appending the order code with “-PULSE”, e.g. “PX200-P200-PULSE”. Figure 1. Maximum pulse duration versus peak current for each voltage span... -

Page 13: Voltage Limits
For example, a PX200-N100-P100 (with a +/-100V output range) will output +100V and -100V on HV+ and HV- respectively. For amplifier configurations where the HV- output is zero (e.g. - Page 14 ���� where �� is the peak-to-peak displacement of the bender. ���� References A New Electrical Configuration for Improving the Range of Piezoelectric Bimorph Benders; S.

Page 16: Rack Mounting
16 Rack Mounting The PX200 can be installed in a 19-inch x 2U rack space using the single unit rack kit (order code: SingleRackKit-2U). Two amplifiers can also be installed in a side-by-side configuration using the double unit rack kit (order code: DoubleRackKit-2U).
