Product Description
Woodward 8290-195 EPG Speed Control System
Product Overview
- The Woodward 8290-195 is an Electrically Powered Governor (EPG) Speed Control System, designed for precise speed regulation of diesel or gas engines in industrial applications such as power generation, marine propulsion, and industrial processes. This microprocessor-based control unit is part of Woodward’s EPG series, which integrates a speed control unit with an actuator for reliable and efficient engine speed management. The 8290-195 is optimized for use with Woodward’s EPG actuators, providing isochronous speed control for single-engine applications. It is suitable for both new installations and retrofits, offering a compact design, robust performance, and basic diagnostics for reliable operation in demanding environments. The 8290-195 is distinct from Woodward’s 2301D/E series (e.g., 8273-1011), 505D series (e.g., 8200-1300), Peak150 series (e.g., 8200-176), ProAct series (e.g., 8237-2595), 723PLUS series (e.g., 8270-1013), and MicroNet systems (e.g., 5541-693), focusing on cost-effective speed control without load-sharing capabilities.
