We recently acquired a large inventory of overstock items and spare components. These items were originally designated for installation on a vessel undergoing a major refit and repower project. When the project was halted before completion, all components were placed into storage.

This item may have been briefly mounted during the initial fitting stage of the refit, as evidenced by faint circular witness marks around the mounting holes. However, we do not believe it was ever placed into service. The internal electrical connections and terminals remain untouched and show no signs of wiring or permanent installation, indicating the unit was, at most, temporarily test-fitted before being removed and stored. Please review the photos carefully for the item's overall condition.

Please note that the two different manufacturer identification tags on this unit may be somewhat confusing. Based on our research, we believe the unit was designed and manufactured by Danfoss and then specified to meet Rolls-Royce Marine Automation requirements. We recommend carefully reviewing both manufacturer tags and verifying the part numbers and specifications. If possible, please contact the manufacturer to confirm compatibility with your specific application before purchasing.

This frequency controller is part of a complete Rolls-Royce steering assembly. We have additional components from this steering system available in separate listings. If you are looking to complete or expand your existing system, please feel free to contact us, as we may have the additional components you need.
