Industrial Applications

1. Synchronized Material Handling Conveyors

Utilizing the 5.5 kW output and high starting torque via sensorless vector control, the VFD precisely regulates the speed of heavy conveyor belts in manufacturing plants. Its built-in logic programming reduces the need for external PLCs for simple conveyor sequencing.

Problem Solved

Eliminates jerky starts and speed inconsistencies under varying heavy loads, preventing material spillage and reducing mechanical wear on the conveyor drivetrain.

2. Variable Flow Centrifugal Pumping

Operating with a three-phase 400V power supply, the drive dynamically adjusts pump motor speeds up to 590 Hz based on real-time fluid demand using its 4-20mA analog inputs connected to pressure sensors.

Problem Solved

Reduces energy waste by matching pump output to actual system demand instead of running continuously at full speed and throttling with mechanical valves.
