Description
The Woodward 2301D Digital Load Sharing & Speed Control 8273-140 is a microprocessor-based generator control module designed for engine speed regulation and load sharing applications. It controls generators driven by diesel or gas engines and provides advanced digital control functions compared with traditional analog 2301A systems. The 8273-140 version is configured for 24 VDC input and ordinary location installation.
The 2301D controller supports isochronous operation, droop speed control, base-load control, and soft load transfer during generator paralleling operations. It is commonly used in industrial power generation, marine generator systems, and engine-driven equipment requiring stable speed and load management.
