- Description: 2301D Digital Load Sharing and Speed Control, 24 VDC Input, Ordinary Locations
Overview
- The Woodward 8273-501 is a 2301D Digital Load Sharing and Speed Control module designed to regulate the speed and load of generators driven by diesel or gaseous engines (prime movers). It is used in industrial applications such as power generation, oil and gas, and marine systems, providing precise control and proportional load sharing in parallel generator setups. Its microprocessor-based design enhances flexibility and compatibility with existing 2301A systems.
