Real-time monitoring with fault memory (15 records)
Comprehensive protections: overcurrent, overload, phase loss, grounding
2.Smooth & Efficient Operation
Reduces inrush current and mechanical shock
Adjustable start/stop curves for different load requirements
Improves equipment lifespan and grid stability
3.Intelligent Control System
32-bit ARM processor for precise control
LCD/touch display with real-time data visualization
RS485 + Modbus communication for remote management
1.Daily Maintenance
Regularly check wiring and terminal connections
Ensure proper ventilation and dust prevention
Monitor operating parameters via display system
2.Operational Precautions
Avoid exceeding 3 starts per hour
Ensure correct voltage and environmental conditions
Perform periodic inspection of SCR modules
The MV Solid-State Soft Starter is widely applied in:
Power plants and substations
Steel, metallurgy, and chemical industries
Cement, paper-making, and mining operations
Equipment such as pumps, compressors, conveyors, and mixers
Example: In a steel plant, the MV Solid-State Soft Starter reduces startup impact on large fans, improving system stability and lowering maintenance costs.
