new piezo amplifier: NV 40/3CL
piezosystem jena presents the NV40/3CL piezo amplifier, which was designed for low voltage piezo elements with an external measurement system. The NV40/3CL includes a voltage amplifier, closed loop control, and display with a PC-interface. The high-resolution display shows the position 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 you with the opportunity to operate the piezo element via an analog modulation input. The position of the actuator 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. The new soft start ensures an actuator-safe activation of the system. With the electronic PID controller, this system operates without any drift or hysteresis.
