Industrial Applications

1. High-Speed Conveyor Systems with Dynamic Braking

This power module is ideal for controlling large conveyor systems in manufacturing or logistics, especially those requiring frequent and precise starts/stops and handling heavy loads. The 55kW power rating supports substantial material movement.

Problem Solved

The integrated braking chopper efficiently dissipates regenerative energy generated during rapid deceleration, enabling quick, precise stops and preventing damage to the drive. The high overload capability (up to 200% for 3 seconds) ensures reliable startup and operation under peak load conditions.

2. Variable Speed Pump Control for Industrial Utilities

The module can precisely regulate the speed of large pumps in industrial water treatment facilities, HVAC systems, or other fluid transfer applications, optimizing energy usage and flow rates.

Problem Solved

Variable frequency control (up to 550 Hz V/f control) allows for accurate flow regulation, significantly reducing energy consumption compared to traditional on/off or throttled systems. The 200-240V input voltage is compatible with many industrial power grids, and the 55kW output handles substantial pumping demands. The IP20 rating makes it suitable for integration within protected electrical cabinets.

3. Precision Mixer and Agitator Drives in Process Industries

This power module is well-suited for driving large mixers or agitators in chemical, pharmaceutical, or food processing, where consistent product quality relies on precise speed and torque control.

Problem Solved

The vector control capability (up to 200 Hz) provides strong and stable torque, especially at low speeds, which is critical for starting and mixing viscous or high-density materials. The robust 55kW output and high overload capacity allow the drive to manage sudden changes in material viscosity or batch size without compromising performance.
