Overview
The EG3000 is a KUTAI (固也泰) electronic closed-loop speed governor, the enhanced variant of EG2000 with optimised PID default values for heavy-duty applications. It uses DIP-switch-selectable frequency bands (600–1200 / 1200–2500 / 2500–5000 / 5000–9500 Hz) and includes smoke-suppression start-up logic.
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
