Product Description
Woodward PCU2000ETH V4.5.0 Power Control Unit
Product Overview
- The Woodward PCU2000ETH V4.5.0 is a Power Control Unit designed for advanced control and monitoring of power generation systems, particularly for gas turbines, diesel engines, and generator sets in industrial applications such as power plants, marine propulsion, and critical infrastructure. This microprocessor-based control unit integrates engine control, generator management, and power distribution functions, offering precise synchronization, load sharing, and protection capabilities. The "ETH" designation indicates Ethernet communication support, and "V4.5.0" refers to the firmware version, which includes enhanced features and performance improvements over earlier versions. The PCU2000ETH is suitable for single or multi-unit configurations, providing robust communication protocols for seamless integration into SCADA and DCS systems. Compared to Woodward’s EasyGen series (e.g., EasyGen-3500-5, 8440-2087) or EGCP-2, the PCU2000ETH is tailored for more complex turbine and engine control applications with advanced networking capabilities. It is distinct from Woodward’s protection relays (e.g., MRI4A0AB), excitation systems (e.g., DECS-100-B15), electronic governors (e.g., DYN1-10784-003-0-12), and actuators (e.g., 8408-921).
