Piezosystem Jena NV 40/3 Analog 3-Channel Piezo Voltage Amplifier – High-Precision Driver for Nanopositioning Systems
This used Piezosystem Jena NV 40/3 is a precision 3-channel piezoelectric voltage amplifier designed for controlling low-voltage piezo actuators and nanopositioning stages . The amplifier provides independent control of up to three piezo elements with an output voltage range of -20 to +130 V and a continuous output current of 40 mA per channel .
With an ultra-low voltage noise of <0.3 mVrms at 500 Hz, the NV 40/3 achieves sub-nanometer positioning resolution, making it ideal for applications in atomic force microscopy, interferometry, precision alignment, and semiconductor inspection . The unit features a dimmable TFT display, analog modulation inputs, and computer control via USB and RS232 interfaces .
The NV 40/3 incorporates special protective circuits including soft-start to prevent voltage spikes during power-on/off, short-circuit protection, and thermal overload protection for actuator-safe operation .
Condition Note: This unit is untested and sold as-is. This listing is for the amplifier unit only. Complete systems typically include power supply, cables, and software.
