Industrial Applications

1. Small Conveyor Systems for Material Handling

This drive precisely controls the speed of small conveyor belts in manufacturing or logistics, ensuring smooth material flow and preventing jams.

Problem Solved

Fixed-speed conveyors can be inefficient or cause product damage. The V20's 0.55 kW power and variable frequency output (0-550 Hz) allow for optimized speed adjustments, reducing wear on mechanical components and accommodating different product types or production rates. The integrated braking unit enables controlled stops.

2. Industrial Pump Control for Water/Wastewater Treatment

Utilized to regulate the flow rate of pumps in water or wastewater treatment plants, optimizing energy consumption and process control.

Problem Solved

Fixed-speed pumps often operate at maximum capacity, wasting energy and potentially causing excessive pressure. The V20's ability to vary motor speed based on demand (using 0.55 kW power) reduces energy consumption significantly. The IP20 rating is suitable for installation within a protected control cabinet, common in these environments.

3. Fan Speed Regulation in HVAC Systems for Commercial Buildings

Integrated into HVAC systems to modulate the speed of ventilation fans, allowing for demand-controlled ventilation and energy savings.

Problem Solved

Constant-speed fans in HVAC systems consume a lot of energy and provide static airflow. The V20's 0.55 kW motor control with a wide output frequency range (0-550 Hz) allows for dynamic adjustment of fan speed, matching ventilation to actual occupancy or air quality requirements, thereby improving energy efficiency and indoor air quality. Convection cooling is beneficial for quiet operation in building environments.
