Woodward 8406-121 EGCP-2 Engine Generator Control Package
- Manufacturer: Woodward
- Model/Part Number: 8406-121, Revision H
- Description: EGCP-2 Microprocessor-Based Generator Control and Engine Management Package, 50_150 VAC PT Input, 9_32 VDC, for Diesel or Gas Engine Generator Sets
Overview
- The Woodward 8406-121 (Rev. H) is an EGCP-2 Engine Generator Control Package designed for automating and protecting small- to medium-sized diesel or gas engine-based generator sets (up to 30,000 kW). It integrates with an automatic voltage regulator and speed control for comprehensive generator management, supporting stand-alone or utility-paralleled operations. A network of up to eight EGCP-2 units can control unmanned generator sets for base-load, peak shaving, or backup power applications.
