Purpose
The NDR6881 is the dual channel driving unit used for static and dynamic supply of large piezoelectric actuators having capacity up to 200uF. The NDR 6881 is primarily designed as a standalone laboratory desktop unit. It is used for driving or positioning or (in common sense for operating only the piezoelectric actuators/stacks of various types. The device is not designed for use with loads having high energetic losses. The device also cannot be used with piezoelectric actuators having positive energetic balance in long term meaning (energy harvesting).
