A cost-effective draw-out type protection system for small to medium generators, integrating protection, monitoring, metering, and advanced communications. Features 5A phase CT inputs (P5), low-range control power (LO: 20-60V DC/20-48V AC), 4-20mA analog outputs (A20), and enhanced LCD display (E) for real-time monitoring.
- Comprehensive generator protection: stator differential, 100% stator ground, loss of excitation, reverse power, etc.
- Advanced monitoring: 12 RTD inputs for thermal protection, 4 analog inputs for vibration, high-accuracy metering for power parameters.
- Flexible communications: RS232, RS485, 10BaseT Ethernet; supports Modbus RTU/TCP, DNP 3.0.
- User-friendly interface: large sunlight-readable display, LED indicators, keypad for local configuration.
- Draw-out design for minimal downtime during maintenance.
