Core Function for Speed Regulation

The Woodward 8290-184 is a precision speed governor from the EPG series for diesel and gas engines. This unit regulates the fuel supply to maintain stable rotational speed under varying load conditions. It ensures optimal performance and efficiency of the prime mover in demanding applications. Consequently, it is critical for applications requiring precise isochronous (constant) speed control.

Compatible Actuators and Electrical Specifications

This governor is compatible with key Woodward actuators including models 1712, 1724, 512, and 524. It operates from a 24VDC power supply with a wide input range from 20 to 32 VDC for stability. The 8290-184 consumes up to 95 watts of power and includes a 10A slow-blow fuse for protection. Furthermore, its design includes features like Start Fuel Limit to minimize smoke during turbine startup.

Detailed Technical Specifications

Engineered for harsh environments, this governor can be mounted directly on the engine. It functions reliably across an extreme ambient temperature range from -40°C to +70°C. The following table details its comprehensive electrical, performance, and compatibility parameters.

Application and Installation Notes

This governor is ideal for generator sets, pump drives, and compressor packages requiring tight speed regulation. For installation, use 12 AWG wiring for runs over 10 feet and 14 AWG for shorter connections. The Woodward 8290-184 provides reliable, closed-loop control for maintaining consistent power output. Therefore, it is a fundamental component for power generation and industrial mechanical drive systems.
