Piezo controller and amplifier : piezo controller 3-channel version : NV 40/3

The piezo amplifier NV 40/3 was designed for controlling low voltage piezo elements. The NV 40/3 includes voltage amplifier, a display, a PC-interface. The high-resolution display shows the voltage of the actuator along with some other information such as: the mode of operation, and the temperature inside the amplifier.

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

Due to the very low voltage noise of the output current, only 0,3 mVRMS this amplifier system 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-circuit. T

he new soft start ensures an actuator-safe activation of the system.
Due to its design, and compact casing, the new amplifier is recommendable for all R&D and engineering applications.
