The NV40/3 piezo amplifier was designed for controlling low voltage piezo elements. It includes a voltage amplifier, a display and a PC-interface. The high-resolution display shows the voltage of the actuator, along with the mode of operation and the temperature inside the amplifier.

This amplifier also provides the opportunity to control the piezo element via analog modulation input or RS232. The actuator voltage can be viewed via the monitor output.

Due to the very low voltage noise of the output current, only 0.3 mV rms, the amplifier is ideally suited for positioning applications with sub-nm resolution. Special protective circuits prevent voltage spikes when switching the unit on and off and consequently avert any overload caused by overheating or short-circuiting. This soft-start ensures an actuator-safe activation of the system.

Due to its design and compact casing, the amplifier is recommendable for R&D and engineering applications.
