Product Features

Wide Application: Suitable for speed control of various power equipment such as diesel engines, gas engines, steam turbines, or gas turbines. Applied in generator sets, compressors, pump stations, ships, locomotives, etc.
Flexible Signal Input: Sets equipment speed or load based on 4-20mA or 1-5Vdc computer control signals, offering multiple options to meet diverse control needs.
Diverse Working Modes:

Isochronous Regulation: For constant speed control, suitable for single-unit operation or multiple prime movers in isolated grids.
Droop Regulation: Provides flexible control for parallel operation and load distribution.

High Integration: Works with Woodward devices (e.g., power transfer switches, I/O controllers, generator load controllers) for comprehensive system control.
Rich Functions: Includes synchronization/deceleration control, high-low speed adjustment, fuel-limited overspeed start, etc., beyond basic speed/load control.
High-precision Output: Output signals proportional to fuel settings for desired speed/load ensure precise control.
Rugged Design: Withstands harsh industrial environments, operating stably at -20°C to 70°C.
User-friendly Operation: Built-in HMI with color LCD and soft keys, featuring multi-level password protection against unauthorized changes.

Technical Parameters

Input Signals: Supports 4-20mA/1-5Vdc for speed/load setting, and receives magnetoelectric/Hall speed sensor signals for real-time speed monitoring.
Output Signals: Analog (4-20mA/0-10V) or digital (relay outputs) proportional to fuel settings, driving actuators like fuel valves and servo motors.
Working Modes: Isochronous regulation and droop regulation.
Communication Interfaces: Supports RS-232/485, Modbus, Ethernet, etc. Compatible with SAE-J1939/Modbus RTU for seamless integration with engine ECUs and SCADA systems.
Operating Temperature: -20°C to 70°C.
Power Supply: 12/24Vdc.
Dimensions & Weight: Approx. 16cm×16cm×12cm, 0.8kg.
Other Features: Three configurable PID controllers for kW/kvar input/output control, and MCB/GCB synchronization (slip/phase matching).

Application Scenarios

Power Generation: Precisely controls engine speed in diesel/gas generator sets to stabilize voltage/frequency. Enables balanced load distribution via droop regulation for parallel generators, enhancing system reliability.
Industrial Power: Controls speeds of engines/turbines driving compressors/pumps, ensuring stable power output for industrial processes.
Marine Propulsion: Regulates main engine speed and propeller load matching, optimizing ship performance under various conditions (navigation, berthing, anchoring).

Common Faults and Solutions

Causes: Faulty speed sensor, improper PID parameters, or actuator failure.
Solutions: Check sensor installation/wiring, test output signals; reset PID to defaults and fine-tune; inspect actuator flexibility and replace if jammed.

Causes: Damaged interface, mismatched protocols, or faulty cables.
Solutions: Check interface for looseness/oxidation; verify baud rate/parity settings; replace damaged cables.

Causes: Abnormal input voltage or faulty power lines.
Solutions: Measure voltage within rated range; repair/replace open/short-circuited power lines or modules.
