NV120/1 – Description

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

These amplifiers provide a permanent output current of 120 mA, with a signal noise of <0.3 mV @ 500 Hz. It achieves position resolution in the sub-nm range in addition to a settling time in the microseconds range.

The NV120/1 piezo controllers are 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.

For user flexibility various control options are included. A manual control, as well as an analog control, and various digital interfaces are available. The NV120/1 has two types of amplifiers. The NV120/1 is intended for actuators without an integrated measurement system.

The NV120/1 CLE has automatic sensor identification – the integrated ASI-functionality. It is designed for use with piezo actuators that have an integrated measurement system. It can be either a high-resolution strain gauge sensor or a non-contact capacitive sensor.
