FAQ
Q: What is the Woodward 9905-387?
A: The 9905-387 is a Woodward 2301A electronic speed and load-sharing control designed for engine-driven generator applications.
Q: What is the main function of the 9905-387?
A: It regulates prime-mover speed by processing the engine-speed feedback signal and controlling the connected actuator. It can also participate in load-sharing arrangements when generators operate in parallel.
Q: What type of speed feedback does it use?
A: The controller uses a magnetic pickup (MPU) to obtain engine-speed feedback. The frequency of the pickup signal is used to determine actual engine speed.
Q: What is the required power supply?
A: The 9905-387 is designed for a nominal 24 VDC supply, with a commonly specified operating range of approximately 18–32 VDC.
Q: Does the 9905-387 support droop and isochronous operation?
A: Yes. The 2301A control platform supports both operating modes. Droop is generally used for coordinated load sharing, while isochronous control maintains essentially constant speed when the application requires it.
Q: Can the 9905-387 be used with diesel engines?
A: Yes. It is intended for compatible diesel and gas engines, provided the actuator, speed sensor and engine fuel-control system meet the controller’s requirements.
Q: Is the 9905-387 suitable for generator parallel operation?
A: Yes. Its load-sharing capability makes it suitable for generator sets operating in parallel, where coordinated speed and load control is required.
Q: What are the dimensions and weight of the 9905-387?
A: The commonly referenced dimensions are approximately 241 × 165 × 64 mm, with a weight of about 1.85 kg. The exact mounting dimensions should be checked against the specific hardware revision before installation.
