Industrial Applications

1. High-Speed Conveyor Systems with Frequent Stops/Starts

This power module is ideally suited for controlling motors in conveyor systems that require frequent acceleration and deceleration cycles. The integrated braking chopper efficiently dissipates regenerative energy, preventing component damage and ensuring smooth, controlled stops. The Class A filter minimizes electromagnetic interference, crucial for reliable operation in complex industrial environments.

Problem Solved

Prevents overheating and damage from regenerative energy during frequent braking, while maintaining stable operation and complying with electromagnetic compatibility standards in high-dynamic applications.
