Industrial Applications

1. Conveyor Belt Systems

This variable frequency drive is ideal for controlling conveyor belt motors in material handling applications. Its 1.1 kW rated power is suitable for moderate loads, while precise speed control (0-550 Hz output frequency) ensures smooth acceleration/deceleration, reducing wear and tear on mechanical components. The integrated Safe Torque Off (STO) function provides an emergency stop capability for operator safety, and the IP20 rating is sufficient for controlled indoor environments.

Problem Solved

Provides precise speed control and safe operation for conveyor motors, optimizing material flow and enhancing operator safety during maintenance or emergencies.
