Overview
The 4296675 is a high-power Cummins EFC-series electronic speed governor for K19 and KV38 large diesel engines. It drives high-current EFC actuators and is built for prime-power and continuous-duty applications in power plants and heavy industry.
Key Features
- 8A High-Current Output — Drives larger EFC actuators and high-torque fuel pumps found on Cummins KTA38, KTA50, and QSK series engines
- 16–32V DC Power — Optimized for 24V heavy-duty generator electrical systems with low-voltage transient ride-through
- Overspeed Protection — Configurable RPM threshold (1500–7500Hz) with 1.5-second delay prevents engine runaway
- Soft-Start Ramp — Smooth engine acceleration limits startup current draw and reduces visible exhaust smoke
- MPU Signal Diagnostics — LED status indication for magnetic pickup signal quality simplifies installation and troubleshooting
- Direct OEM Replacement — Form/fit/function identical to Cummins 4296675 EFC governor unit
