Key Features

1. Low‑voltage wide‑range power supply: 18–40 VDC (24 VDC nominal), power consumption 40 W, inrush current 7 A (0.1 ms)

2. Master gateway function: centralized management of multi‑genset DSLC network, system‑level load distribution & synchronization coordination

3. Dual magnetic pickup (MPU)/proximity switch speed inputs for high‑reliability speed monitoring

4. Dual LON bus channels for DSLC/MSLC network communication; 3 serial ports (RS‑232/422/485) supporting Modbus RTU/ASCII for HMI and remote monitoring

5. Isochronous (constant‑speed) & droop control modes, integrated engine overspeed protection, fuel limiting and fault self‑diagnosis

6. Conformal‑coated PCB, anti‑vibration, EMI‑resistant, suitable for marine, offshore oil‑gas and heavy‑duty industrial environments
