The Jena NV40/3 is a compact, 3-channel analog piezo controller that delivers precise nanometer-scale actuator positioning with sub-nanometer resolution and millisecond settling time. It provides -20 V to 130 V output across three independent channels, each rated for 40 mA continuous current, with exceptionally low voltage noise below 0.3 mV RMS at 500 Hz. The device features a dimmable 3.5-inch TFT color display presenting real-time actuator voltage, operating mode, and internal temperature monitoring.

## Compatibility & Integration
Two versions serve different application requirements: the standard NV40/3 controls low-voltage piezo elements without integrated measurement systems, while the NV40/3 CLE variant includes automatic sensor identification (ASI) for strain gauge and capacitive sensor actuators, enabling actuator exchange without recalibration on ASI-compatible products.
Software support includes LabVIEW drivers, DLL/.Net Framework libraries, and Micromanager compatibility for flexible laboratory and OEM integration.
