Industrial Applications

1. Conveyor Belt Systems in Warehouses

This VFD is ideal for controlling the speed of asynchronous motors driving conveyor belts in automated warehouse and logistics operations. The 1.1 kW power rating is suitable for many light to medium-duty conveyor segments.

Problem Solved

Precise speed control (0-550 Hz output frequency) allows for optimized material flow, reducing product damage and energy consumption. The 150% overload capability for 60 seconds handles startup torque and temporary jams without tripping. The integrated braking chopper allows for controlled stopping and emergency braking, crucial for safety and process efficiency. Its IP20 rating is suitable for installation within control cabinets, protecting it from dust and accidental contact in an industrial environment.

2. Small Industrial Pumps for Fluid Transfer

The VFD can be used to regulate the flow rate of small to medium-sized industrial pumps, such as those used for water treatment, chemical dosing, or coolant circulation in manufacturing processes.

Problem Solved

Variable speed control prevents cavitation and water hammer, reduces wear on mechanical components, and significantly lowers energy consumption by matching pump output to demand, instead of throttling. The 3-phase 380-480V input and 1.1 kW output are common requirements for such pumps. IP20 ensures protection within a control panel located in a processing area.

3. Industrial Fan Control for HVAC/Ventilation Systems

This drive is well-suited for controlling the speed of fans in industrial heating, ventilation, and air conditioning (HVAC) systems or general industrial ventilation.

Problem Solved

Modulating fan speed allows for precise control of airflow and pressure within a building or process, optimizing air quality and temperature while drastically reducing energy consumption compared to constant-speed operation with dampers. The 1.1 kW power and 380-480V input are typical for smaller industrial fans. The IP20 protection is appropriate for installation in an enclosed electrical panel in a plant room.
