Description
The Woodward 8256-017 is a precision-engineered Speed Control Module designed specifically for 12-volt battery-operated systems. As a key component of the EPG (Electric Power Generation) series, it provides reliable isochronous speed control, maintaining constant engine RPM regardless of the load applied. This model is highly valued for its ability to ensure stable frequency in isolated generation; however, when configured for parallel operation with other generators, it requires the integration of an external Generator Load Sensor to maintain system synchronization and prevent load-sharing conflicts.
Product Specifications
- Weight: Approximately 0.85 kg (1.87 lbs)
- Dimensions: 130 mm x 110 mm x 50 mm
- Voltage: 12V DC nominal
- Origin: Primarily manufactured in the United States
Frequently Asked Questions
💡 What makes the 8256-017 ideal for isochronous control? Isochronous control means the governor maintains a zero-droop characteristic, keeping the engine speed perfectly steady at the setpoint regardless of the electrical load. The 8256-017 achieves this by rapidly calculating the required fuel adjustment to counteract speed dips or surges.
⚙️ Why is a Generator Load Sensor necessary for parallel operation? When running in parallel, generators must share the electrical load proportionally. Without a load sensor, the governor cannot “see” the external load demand, which would cause the unit to struggle to maintain its share, potentially leading to instability or reverse-power conditions.
🛠️ Is the 12V requirement strict? Yes. This unit is specifically calibrated for a 12V electrical architecture. Operating this module on a 24V system without appropriate power regulation will likely result in permanent damage to the internal circuitry and control components.
🌐 How do I ensure the best performance during system startup? Ensure that the magnetic pickup signal is clear of electrical noise and that the governor’s PID (Proportional-Integral-Derivative) parameters are tuned to the specific mechanical response time of your engine’s fuel injection system.
