Product Performance
Speed Control Accuracy: High accuracy in speed stabilization under full-load fluctuations, response time for load sudden changes < 50ms, rapid correction of fuel throttle quantity;
Start-up Protection: Standard start-up fuel limit, prevents excessive fuel injection during cold engine start and reduces black smoke and cylinder body wear;
Interference Resistance: Reinforced industrial housing, resistant to vibration and electromagnetic interference, suitable for harsh conditions in the field / engine compartment;
Expandability: Optional slope generator, customizable acceleration curve; supports 4-20mA analog signal connection to DCS/SCADA system;
Control Logic: Pure hardware closed-loop PID speed control, no program firmware, low failure rate, no need for software debugging.

Application Fields
Power Generation Industry: Fixed diesel generator sets, gas turbine backup power stations, mine / oilfield self-owned power stations (grid-connected / off-grid units);
Ship Power: Auxiliary generator sets for ships, emergency diesel generator sets for ships;
Industrial Power: Gas compressors, diesel-driven industrial pumps, fixed industrial power units for construction machinery;
Oil and Gas Field: Oilfield wellhead diesel power equipment, gas power skid-mounted units.
