Industrial Applications

1. Conveyor Belt Systems with Frequent Starts/Stops

This power module is ideal for controlling conveyor belts in manufacturing or logistics, especially those requiring frequent acceleration and deceleration cycles. Its robust overload capabilities (e.g., 150% for 57s, 200% for 3s for HO rated power) handle high starting torques and braking energy associated with moving heavy loads or stopping quickly.

Problem Solved

Prevents motor and drive damage due to high inertial loads and frequent stops, ensuring smooth and reliable material transport. The integrated braking chopper also dissipates excess energy during deceleration, protecting the system.

2. Fan and Pump Control in HVAC/Water Treatment

The module can efficiently control variable speed fans in large HVAC systems or pumps in water/wastewater treatment plants. The 3-phase, 380-480V input and 5.5 kW (LO) / 4 kW (HO) rated power are suitable for medium-sized industrial motors. Its high efficiency (0.97) and internal air cooling make it suitable for continuous operation in plant environments.

Problem Solved

Optimizes energy consumption by precisely matching motor speed to demand, reducing wear on mechanical components, and providing stable flow/pressure control. The Class A filter helps maintain power quality.

3. Textile Machinery and Extruders

For applications requiring precise speed and torque control, such as textile machines (e.g., spinning, weaving) or plastic extruders. The vector control capabilities (0-200 Hz) allow for fine adjustment of motor speed, which is crucial for product quality and process consistency. The IP20 rating is suitable for installation within control cabinets in typical industrial settings.

Problem Solved

Ensures high precision in manufacturing processes by maintaining constant speed or torque under varying loads, leading to consistent product quality and reduced waste.
