- Vibration: 4 Gs, 5 to 500 Hz. Shock: 60 Gs.
- Weight: Approximately 1.8 kg (4 lb).
Functional Features:
- Simultaneously implements speed control of the prime mover and load sharing during multi-unit parallel operation.
- Speed Control: Maintains stable speed of the prime mover.
- Load Sharing: Ensures proportional load sharing when multiple units operate in parallel.
Application Scenarios: Load sharing and speed control for diesel generators, gasoline generators, steam turbine power generation, and gas turbine power generation.
Working Principle: Through an electronic control circuit, it monitors generator output and prime mover speed, automatically adjusting the fuel supply to achieve precise speed and load control.
