Industrial Applications

1. Dynamic Conveyor Systems with Frequent Starts/Stops

This power module is ideal for controlling motors in conveyor systems that require frequent acceleration, deceleration, and precise positioning. The 4kW High Overload rating (200% for 3s, 150% for 57s) ensures robust performance during intermittent heavy loads, while the built-in braking chopper efficiently dissipates regenerative energy, extending motor lifespan and improving system safety.

Problem Solved

Prevents motor and drive damage from high inertia loads and frequent braking cycles, ensuring smooth and controlled material handling.

2. Energy-Efficient HVAC and Pumping Systems

For industrial heating, ventilation, air conditioning (HVAC) systems, and pump applications, this module enables precise variable speed control. The 5.5kW Low Overload rating supports continuous operation with varying fluid or airflow demands, and the 0-550 Hz V/f control output frequency allows for fine-tuning of motor speed, leading to significant energy savings and optimized process control.

Problem Solved

Optimizes energy consumption and operational efficiency by adjusting motor speed to match demand, rather than running at constant full speed.

3. Compact Machine Integration with Custom Filtering Needs

The compact FSC frame size (355 x 140 x 165 mm) makes this power module suitable for integration into control cabinets with limited space, often found in smaller machines or distributed automation setups. Its unfiltered design provides flexibility for engineers to select external filtering solutions tailored to specific electromagnetic compatibility (EMC) requirements of the installation environment.

Problem Solved

Addresses space constraints in industrial cabinets and offers flexibility for application-specific filtering, reducing overall system footprint and cost for specialized environments.
