Industrial Applications

1. Conveyor Belt Speed Control in Manufacturing

This power module can precisely control the speed of a 2.2 kW (LO) three-phase AC motor driving a conveyor belt system in a factory. The adjustable output frequency (0-550 Hz V/f control) allows for fine-tuning of material flow, while the IP20 rating requires it to be mounted within an existing control cabinet, which is standard for manufacturing environments. The integrated braking chopper efficiently handles deceleration.

Problem Solved

Enables variable speed control for optimal production rates and energy efficiency, adapting to different product types or stages, and the integrated braking chopper handles deceleration quickly and safely.

2. Pump Control in HVAC Systems for Commercial Buildings

The SINAMICS PM240-2 can manage a 1.5 kW (HO) pump motor, adjusting its speed based on demand in a building's heating, ventilation, and air conditioning (HVAC) system. Its 380-480V input and integrated Class A filter make it suitable for typical commercial power grids, and its IP20 rating is appropriate for installation inside an electrical panel.

Problem Solved

Optimizes energy consumption by only running pumps at the necessary speed to maintain desired flow rates or pressures, reducing wear and tear on mechanical components, and providing precise control for comfort and efficiency.

3. Industrial Mixer/Agitator Speed Regulation in Chemical Processing

For small to medium-sized industrial mixers or agitators in chemical processing, this 2.2 kW power module can provide reliable and precise speed regulation for a 3-phase AC motor. The ability to handle high overload conditions (150% for 57s) is crucial for starting viscous mixtures, and its internal air cooling is adequate for controlled process environments when properly integrated into a cabinet.

Problem Solved

Allows for precise control over mixing intensity and duration, which is critical for product quality and consistency in chemical formulations, while the overload capability ensures robust operation even with challenging material properties.
