Industrial Applications

1. Conveyor Systems with Dynamic Loads

This power module is ideal for controlling motors in conveyor systems that experience frequent starts, stops, and changes in speed, requiring rapid deceleration. The built-in braking chopper efficiently dissipates regenerative energy during deceleration.

Problem Solved

Prevents overvoltage faults and allows for quick and controlled stopping or reversing of heavy loads due by efficiently dissipating regenerative energy. The high overload capacity (200% for 3s) handles peak torque demands during startup of loaded conveyors.

2. Energy-Efficient Pump and Fan Control

Suitable for variable speed control of pumps and fans in industrial HVAC systems or water/wastewater treatment plants to optimize energy consumption and process flow.

Problem Solved

By precisely controlling motor speed (output frequency 0-550 Hz), the system can adjust flow or airflow according to demand, reducing energy waste compared to fixed-speed operations. The 11 kW rated power is appropriate for medium-sized pump and fan applications.

3. Medium-Duty Machine Tool Spindle Control

Can be employed for controlling the spindle motors of medium-duty machine tools (e.g., smaller lathes, milling machines) where precise speed regulation and occasional high torque bursts are needed.

Problem Solved

The vector control capability (0-200 Hz) allows for accurate speed and torque control required for machining operations. The high overload capacity (150% for 57s) supports short-duration cutting forces, while the robust 380-480V input ensures compatibility with typical industrial power grids.
