Overview
The 3044196 is a Cummins EFC-series electronic speed governor for diesel generator sets up to ~350 kW. Designed for PT-pump engines, it provides stable isochronous operation for prime and standby power.
Key Features
- PT(G) Fuel System Control — Specifically calibrated for Cummins PT(G) mechanical fuel pumps with EFC electronic actuator interface
- ≤350kW Power Rating — Optimized for mid-range diesel generator sets with Cummins 6BT, 6CT, and NTA855 series engines
- Speed Stability ±0.25% — Maintains precise RPM control from no-load to full-load with rapid transient recovery
- Soft-Start Ramp — Configurable acceleration profile reduces startup smoke and mechanical stress on fuel system components
- 12/24 VDC Auto-Sensing — Compatible with standard generator control battery voltages without external converters
- Drop-In OEM Replacement — Direct replacement for Cummins 3044196 governor with identical connector pinout and mounting dimensions
