Overview
The 3044195 is a Cummins EFC-series electronic speed governor for PT(G)-type fuel systems on gensets up to ~500 kW. It provides stable isochronous operation for prime and standby power applications.
Key Features
- ≤500kW Rating — Designed for mid-size diesel generator sets with Cummins 6CT, 6LT, and NTA855 series engines
- Closed-Loop PID Control — Proportional-Integral-Derivative algorithm provides precise RPM regulation with configurable gain settings
- Mechanical Pump Interface — Directly drives Cummins PT(G) fuel pump rack via EFC actuator for fast fuel metering response
- Soft-Start — Adjustable acceleration ramp reduces startup emissions and limits fuel pump mechanical stress
- 12/24V Operation — Dual-voltage auto-sensing power supply for universal generator battery system compatibility
- Drop-In OEM — Form/fit/function replacement for Cummins 3044195 EFC speed governor unit
