Chinook Controller

High-Power Digital Controller

Available as a single- or dual-bay cabinet, the Chinook® controller is a high-power digital magnetic bearing control system recommended for rotating machinery in the power range 10 MW to 25 MW.

The controller provides simple and fail-safe integration of the control cabinet with the machine station via digital output/input, and its high processing performance allows for complex algorithms that provide high dynamic efficiency and noise immunity.

The controller also offers an automated commissioning and tuning process, built-in condition monitoring and remote adjustment capabilities.
