The UC45 board uses a microcontroller to provide fully digital control of piezo-actuators at a rate of 10kSps. It features ADC and DAC with 16bits resolution, for applications where high resolution is required, such as ultra-precise positioning.
Sampling frequency: 10kSps; A/D converters: 2; D/A converters: 1; Computer interface: USB
The UC55 board has the same format than the UC45, but it features a higher control rate and it exists in three different versions: single channel, dual channel, and triple channel. In single channel, the control rate is 30kSps, in dual channels, 15kSps, and in triple channels, 10kSps. The UC55 boards can also be stacked to handle several independent control channels at high frequency (up to 3).
Sampling frequency: 10/15/30 kSps; Computer Interface: USB type B
The new UC65 controller is a board dedicated to be plugged in the 75 rack family. It is based on a powerful DSP core and can control up to 3 independent or coupled channels. It offers a very fast control capabilities with sampling rates up to 60kSps for 1 channel. It features ADC and DAC with 16bits resolution, for applications where high resolution is required, such as ultra-precise positioning.
