The piezo amplifiers series NV120/1 and NV 120/1 CLE series are engineered to meet the highest standards of accuracy and dynamics for high-resolution piezoelectric actuators.

The piezo amplifiers series NV120/1 and NV 120/1 CLE provides a permanent output current of 120mA and has a signal noise of only <0.3 mV @ 500 Hz. With these excellent signal parameters, it achieves position resolution in the sub-nm range in addition to a settling time in the microseconds range.

The NV 120 series of piezo controller units is designed to be compact table top systems in a rugged metal housing. To accommodate use in laboratory conditions, the amplifiers have a dimmable TFT display.

To give the user flexibility, various controlling options were included. A manual control, as well as an analog control, and various digital interfaces are available. The NV 120 series has two types of amplifiers. The piezo amplifiers NV 120/1 is intended for actuators without an integrated measurement system. The NV 120/1 CLE type has automatic sensor identification, the integrated ASI-functionality. It is designed for use with piezo actuators which have an integrated measurement system. It can be either a high-resolution strain gauge sensor or a non-contact capacitive sensor.
