Industrial Applications

1. High-Power Conveyor Systems

This power module is ideal for controlling large industrial conveyor belts requiring precise speed regulation and quick stopping capabilities. The 90 kW (LO) / 75 kW (HO) power output ensures sufficient torque for heavy loads, while the 380-480V input matches typical industrial supply. The built-in braking chopper provides controlled deceleration.

Problem Solved

Efficiently handles heavy material transport and enables safe, controlled deceleration of large loads using the built-in braking chopper, preventing wear and tear on mechanical brakes and reducing cycle times.

2. Large Industrial Pump and Fan Applications

Suitable for controlling high-capacity pumps and industrial fans in water treatment plants, HVAC systems, or manufacturing processes. The wide output frequency range (0-550Hz for V/f control) allows for optimized flow and pressure control, matching demand and saving energy.

Problem Solved

Provides energy-efficient operation and precise flow/pressure control for large pumps and fans, dynamically adjusting speed to process requirements. The IP20 rating is suitable for installation within a protective control cabinet.

3. Heavy-Duty Machine Tools and Mixers

The robust 75 kW (HO) power and high overload capability (200% for 3s, 150% for 57s) make it suitable for machine tools, industrial mixers, or extruders that experience sudden load changes and require strong starting torque and rapid deceleration.

Problem Solved

Manages dynamic loads and rapid acceleration/deceleration cycles common in machine tool operations and mixing processes, ensuring consistent performance and preventing motor damage due to overcurrents, facilitated by the built-in braking chopper.
