Overview
The C1000A is a Fortrust (孚创) electronic speed governor for small-to-mid diesel generator sets. Despite its “C” prefix (which resembles Cummins naming), it is a Fortrust product — not a Cummins OEM part. It controls engine speed with fast and precise response to transient load changes, and supports control frequencies from 1000 to 13000 Hz.
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
