Description
Woodward N8576-001
Technical Specifications:
Brand: Woodward
Model: N8576-001
Power Supply: 24VDC or 85-265VAC
Speed Input: Magnetic or optical pickup
Functional Features:
Smart PID Regulation: Built-in adaptive PID algorithms ensure minimal speed recovery time during sudden load changes.
Load Sharing: Supports base load, isochronous, and master-slave load sharing modes.
Comprehensive Protection: Integrates shutdown protection for overspeed, underspeed, low oil pressure, and high water temperature.
Application Scenarios:
Widely used in diesel/gas generator sets, marine auxiliary engines, and distributed energy power stations for speed and load control.
Performance Parameters:
Steady-State Speed Droop: Continuously adjustable from 0% to 5%
Speed Droop Compensation: 0% to 10%
Control Accuracy: ≤ 0.25%
Material Composition:
Flame-retardant engineering plastic housing. Internal circuit boards are treated with conformal coating (moisture, salt spray, and mold resistant).
Structural Features:
Front panel features an LCD display and membrane keypad for local parameter setting and status monitoring. Rear features plug-in wiring terminals.
Working Principle:
Continuously samples speed signals and load current. The microprocessor calculates the required fuel amount via complex control algorithms and outputs a PWM signal to drive the actuator, forming a closed-loop control system.
Installation Requirements:
Install inside a control cabinet, avoiding direct sunlight and severe vibration. Speed signal wires must be routed separately from power cables.
Usage Precautions:
Verify engine parameters (gear teeth, rated speed) before powering up. Save parameters and restart for changes to take effect. Conduct offline simulation tests regularly using dedicated software.
