Page 3: Chaper 1 Overview
With a maximum output voltage of 150 V, the BPA100 amplifier is suitable for use with many of our Thorlabs piezo actuators, chips, and stacks. It was designed for use in liquid dispensing applications, which require the piezo stacks to work at frequencies above 100Hz with a sinusoidal or square wave signal. -
Page 4: Chaper 2 Safety
2.2 General Warnings Warning The BPA100 amplifier is specifically designed to drive the type of capacitive loads that characterize piezo actuators and provide high peak currents for the rapid charge and discharge of the piezo capacitance. It must not be used for applications other than stated in this manual, especially not for driving ohmic (resistive) or inductive loads. -
Page 5: Chaper 3 Getting Started
High electrical currents require suitable connectors and cabling. The unit is fitted with SHV connectors which offer a high degree of safety and protection. A suitable cable (CA3262) is available separately from www.thorlabs.com. A suitable mating connector (T4004, T4005 or T4006) is available separately for use in connecting the piezo device being driven. -

ERROR OVERLOAD 10:1 BPA100 PIEZO AMPLIFIER Fig. 3.2 Front panel INPUT – BNC Connector. Provides connection to the controlling input source. This input allows a -2 V to +10 V signal to drive the output to its full scale -30 V to +150 V. This gives a gain of 15. -
Page 8: Chaper 4 Operation
BPA100 Benchtop Piezo Amplifier Chapter 4 Operation Warning: Risk of Electrical Shock Piezo actuators are driven by high voltages. Voltages up to 150 V may be present at the SHV connector. This is hazardous and can cause serious injury. Appropriate care should be taken when using this device. - Page 9 Chapter 4 Operation 2) 150 V peak-to-peak, 703 Hz sine wave into 10.4 µF capacitive load. 150 V peak to peak sine wave = 53 Volt RMS At 703 Hz, the impedance of the 10.4 µF capacitor is -21.8 (theoretical) Calculated RMS current: 2.43 A 3) 150 V peak to peak, 4 kHz square wave into 1.1 µF capacitive load.
