Industrial Applications

1. Conveyor Systems with Frequent Starts/Stops

This power module is ideal for controlling motors in conveyor systems found in manufacturing or logistics. Its precise motor control and integrated braking chopper allow for accurate positioning and smooth deceleration, which is crucial for handling goods on a production line or sorting facility. The high overload capability (up to 200% for 3s) handles peak loads during acceleration, and the integrated braking chopper efficiently dissipates regenerative energy during frequent stops.

Problem Solved

Prevents damage to products from abrupt stops and starts, enables precise material handling, and dissipates regenerative energy during frequent braking cycles, improving system efficiency and safety in demanding conveyor applications.

2. Pump and Fan Applications in HVAC or Water Treatment

The module's high efficiency (η=0.97) and ability to operate reliably within a wide ambient temperature range of -10 to 50 °C make it highly suitable for controlling pumps and fans in industrial HVAC systems or water/wastewater treatment plants. The variable speed control allows precise adjustment of flow or air volume based on demand.

Problem Solved

Optimizes energy consumption by precisely matching pump/fan speed to demand, reduces wear and tear on mechanical components, and ensures stable fluid/air flow in demanding industrial environments while operating efficiently across a broad temperature range.

3. Small Machine Tools or Packaging Machinery

With its compact design (140x355x165 mm) and excellent high/low overload capabilities, this power module can efficiently drive motors in small machine tools (e.g., milling, drilling) or packaging machines where space is often limited and intermittent peak loads are common. The IP20 rating ensures safe installation within control cabinets.

Problem Solved

Provides robust and precise motor control for fast, repetitive motions, handles dynamic loads during cutting, forming, or packaging operations, and fits into space-constrained industrial machinery, contributing to higher throughput and product quality in a safely enclosed environment.
