3. Product Specifications & Features
3.1 Core Specifications
The WOODWARD EASYGEN-3500XT 8440-2085 is optimized for mid-to-large generator sets (10–2000 kVA), with dual-frequency support (50/60 Hz) fitting global power systems. Its load sharing function enables parallel operation of multiple generators (e.g., data center backup arrays), balancing power distribution and preventing overload. The built-in HMI (with touchscreen option) allows on-site parameter configuration and real-time monitoring of key metrics (voltage, frequency, temperature), simplifying operation.
Dual Ethernet ports separate safety and non-safety communication (e.g., IEC 61850 for grid integration, Modbus TCP/IP for HMI), while wide-temperature operation (-40°C to +70°C) ensures reliability in extreme environments (e.g., cold storage backup, desert power plants).
3.2 Key Features
- Comprehensive Control: Combines voltage regulation, load sharing, and synchronization in one unit, reducing system complexity for generator sets.
- Grid-Ready Design: IEC 61850 compliance enables seamless integration with utility grids, critical for prime power applications.
- Harsh Environment Resilience: IP65 protection and -40°C to +70°C operating range handle dust, water splashes, and extreme temperatures.
- Dual Communication Layers: Redundant Ethernet/RS485 ports ensure secure data transmission, minimizing downtime from communication failures.
- User-Friendly Operation: PowerSuite software and built-in HMI simplify programming, monitoring, and fault troubleshooting for on-site and remote teams.
