Industrial Applications

1. Conveyor Systems in Material Handling

This power module is ideal for controlling high-power conveyor belt motors in logistics centers or manufacturing plants, especially where heavy loads require frequent starts/stops and precise speed control.

Problem Solved

The integrated braking chopper efficiently dissipates regenerative energy during rapid deceleration or stopping of heavy conveyor belts, preventing DC bus overvoltage and enhancing system safety. The dual overload capability allows it to handle peak loads during startup or sudden load changes, ensuring smooth and reliable material flow.

2. Pump and Fan Control in HVAC Systems for Large Buildings

Suitable for driving large pumps and industrial fans in heating, ventilation, and air conditioning (HVAC) systems of commercial buildings or industrial facilities, where efficient fluid/air movement and energy savings are critical.

Problem Solved

The VFD's ability to vary motor speed precisely (0-550 Hz V/f control) allows for optimized flow/pressure control, leading to significant energy savings compared to direct-on-line starters. The integrated Class A filter ensures electromagnetic compatibility (EMC) in sensitive building environments, reducing interference with other electronic equipment. Its robust design (IP20) is suitable for cabinet installation.
