Overview
The C2002 is a Fortrust (孚创) EFC-series electronic speed governor for small-to-mid diesel gensets. It modulates the EFC actuator to maintain precise RPM and includes a soft-start ramp to reduce black-smoke emissions on crank.
Key Features
- 10A Continuous Output — High-current actuator drive for GAC ADC, Barber-Colman, and Woodward proportional actuators up to 10 lb-ft torque
- Overspeed Protection — Adjustable 1500Hz–7.5kHz threshold with 1.5-second delay and automatic fuel cutoff relay output
- Isochronous Speed Control — ±0.25% steady-state stability maintains constant engine RPM from no-load to full-load for precise generator frequency
- Magnetic Pickup Input — 600–9500Hz differential MPU sensing with noise rejection for reliable tachometer signal in electrically noisy generator enclosures
- Soft-Start Ramp — Programmable speed ramp eliminates startup smoke, reduces actuator current surge, and provides smooth engine acceleration
- 12/24V Dual Voltage — Auto-sensing 8–32V DC supply with reverse polarity protection for universal generator application
