Industrial Applications

1. High-Power Centrifugal Pump Control in Water Treatment Facilities

This converter is ideal for controlling large centrifugal pumps (e.g., 110 kW) in municipal water treatment or industrial cooling systems. Its 380-480V, 3AC input, and 110 kW rated power (LO) perfectly match the requirements of such motors.

Problem Solved

Precisely controls pump speed to optimize flow and pressure, reducing energy consumption and mechanical wear on the pump and motor. The IP20 rating is suitable for installation within a protective control cabinet in a plant environment. Safe Torque Off ensures immediate and secure shutdown for maintenance.

2. Large Material Handling Conveyor Drive Control

The SINAMICS G120C can efficiently drive large, heavy-duty conveyor belts in manufacturing or logistics facilities, requiring smooth acceleration/deceleration and precise speed control for material handling. The 110 kW power output and robust overload capabilities make it suitable for dynamic loads.

Problem Solved

Provides smooth starting and stopping for heavy loads, preventing mechanical shock and reducing wear on the conveyor system. The USS/MODBUS RTU fieldbus allows easy integration into existing PLC-based control systems for synchronized operations. The IP20 enclosure is appropriate for mounting inside a control panel away from direct environmental exposure.

3. High-Capacity Industrial Ventilation Fan Control

This compact converter is suitable for managing the speed of large industrial fans (up to 110 kW) used in commercial HVAC systems, mine ventilation, or large-scale exhaust systems where precise airflow control and energy efficiency are critical.

Problem Solved

Allows for demand-driven airflow regulation, significantly reducing energy consumption compared to fixed-speed operations. The 380-480V input and 110 kW output can handle substantial fan loads. The compact design allows for integration into existing control cabinets, and its safety features (STO) improve system reliability and maintenance safety.
