TYPE: UP30C
81-BRO-120
The Nabco EAR-120 Governor Actuator (model EAR-120-RS31, type UP30C) is a precision electromechanical control component designed to regulate engine speed and fuel delivery in response to signals from a governing system. As a core element within a Marine Control System, this actuator converts electronic control commands into mechanical output, maintaining stable engine performance under varying load conditions. Its reliable operation is essential for propulsion management, auxiliary engine control, and overall vessel safety aboard commercial and industrial marine vessels.
Key Features
✓ Functions as a governor actuator, translating electronic control signals into precise mechanical actuation for engine speed and load regulation.
✓ Identified by part reference EAR-120-RS31, type designation UP30C — specific voltage, stroke, and response ratings are subject to confirmation against vessel configuration.
✓ Designed for integration within Nabco governor control systems; compatibility with specific panels or controllers should be verified against the installed system type.
✓ Suitable for installation in engine room environments typical of marine service; mounting arrangement and environmental ratings depend on application configuration.
✓ Direct-replacement servicing supports minimal downtime during scheduled maintenance or unplanned actuator failure, helping restore governor control quickly.
Marine Applications
✓ Main propulsion engine governor control on commercial cargo vessels, tankers, and bulk carriers.
✓ Auxiliary diesel generator speed regulation aboard offshore platforms and support vessels.
✓ Engine management systems on tugboats and workboats requiring responsive load-handling capability.
✓ Controlled fuel delivery systems on ferries and passenger vessels where consistent engine performance is operationally critical.
✓ Retrofit and overhaul projects on vessels running legacy Nabco governor control installations.
