12V40 Controller – Description

The 12V40 controller is designed for piezoelectric actuators used in nano-positioning tasks for industrial applications. Different types of casing, with and without screw slots, and a 19″ rack mount version are available.

The 12V40 requires a main supply voltage of 12 V DC. The piezo controller offers the user the choice to control a piezoelectric element manually or via analog modulation input with a signal of 0 to 10 V DC – with a nearly unlimited step resolution. To support industrial use, all operational elements from the front panel are also available on the rear panel. All sockets are also available on the back so that the amplifiers can be easily integrated into an OEM product line. The output voltage can be supervised on the monitor output. Special circuits are integrated to protect the piezo element from voltage spikes and excessive voltages.

These amplifiers are well suited for sub-nm positioning tasks due to a very low voltage noise of only 0.3 mV rms.

24DV40 – Description

The 24DV40 digital piezo controller is designed to be used as a single unit for quasi-static or dynamic-step positioning applications in laboratories.

For the operation of the actuator a control voltage of -20 V to +130 V and an output current of 40 mA (2 x 40 mA for NanoX® actuators) are supplied.

Connected actuators are controlled via a PC using the integrated USB 2.0 interface. With a 16-bit resolution, the 24DV40 guarantees a high positioning accuracy and low noise.

Actuators are easy to connect to the 24DV40 using D-Sub plugs. Due to the stored information in the EEPROM, the actuator will be automatically recognized. The 24DV40 can be used with actuators equipped with either strain gauge or capacitive sensors, as well as actuators without a measurement system. The 24DV40 also supports actuators based on NanoX® technology.
