Industrial Applications

1. High-Power Pumping Systems

This converter can precisely control large industrial pumps, optimizing flow rates for water treatment, HVAC, or chemical processing. Its 110 kW power rating is suitable for substantial pumping demands, while vector control ensures efficient operation across varying loads.

Problem Solved

Reduces energy consumption and wear on mechanical components in large pumping stations by precisely matching motor speed to fluid demand, rather than using inefficient throttling valves. The integrated STO function enhances safety during maintenance.

2. Material Handling & Conveyor Systems

Ideal for driving heavy-duty conveyor belts or material handling equipment in manufacturing plants or logistics centers. The 110 kW output can handle significant loads, and the high overload capacity (up to 200%) allows for controlled acceleration and deceleration of heavy materials, preventing damage and improving throughput.

Problem Solved

Provides smooth and controlled acceleration/deceleration for heavy conveyor systems, reducing mechanical stress, preventing jams, and allowing for precise positioning of materials. The integrated fieldbus (PROFINET/EtherNet/IP) enables seamless integration into plant automation systems.

3. Large Industrial Fan Control

Suitable for controlling large industrial fans in ventilation systems, exhaust systems, or drying processes. The 110 kW capacity and 380-480V input allow it to power substantial fan motors, while V/f control optimizes air flow and minimizes energy consumption based on process requirements.

Problem Solved

Optimizes energy usage in large fan applications by adjusting motor speed to match air demand, eliminating the need for inefficient damper control. The IP20 rating is suitable for controlled industrial environments, and integrated communication allows for remote monitoring and control.
