Noliac Systems has developed single and dual channel dynamic drivers for piezoelectric actuators, and three standard models are now available for purchasing. One driver is a basic device for e.g. fine adjustment mechanisms, and two are designed as standalone laboratory desktop units.
Basic driver
The basic driver NDR6110 provides full stroke driving capability for:
- benders (bimorphs)
- stacked actuators
- bipolar stacks
- shear mode actuators
The driver is intended as a basic device enabling supply of various piezoelectric actuators with static and dynamics voltage in the range in the range up to ±100V or 0-200V. The driver can be used as a part of fine adjustment mechanism in mechanical positioning equipment with piezo feed, or for other piezo element applications.
Laboratory drivers
The laboratory drivers NDR6880 (single channel) and NDR6881 (dual channel) provides high current, high power, a wide frequency range and galvanic separation of output from other circuitry.
The device is a source of single polarity voltage. Its value is proportional to input signal. The driver consists of two main blocks – the preamplifier and the high voltage stage. The input stage is galvanically separate from the output high voltage part. Signal ground of the BNC connector is connected to device casing. Amplifier output is floating. One of its wires could be optionally grounded externally.
