ABB SDCS-FEX-2A 3ADT311500R1 DC Speed Regulator Excitation Module

Product Introduction

The ABB SDCS-FEX-2A (Part Number: 3ADT311500R1) is a DC speed regulator excitation module developed for integration with ABB’s DCS500 drive systems. As part of the SDCS (Speed Drive Control System) family, this excitation module plays a vital role in regulating the field current of DC motors, providing precise control over motor speed and torque across a wide range of industrial applications.

This excitation module ensures that the motor’s magnetic field is optimized dynamically in real time, enabling smooth transitions in acceleration and deceleration, reliable field weakening, and consistent performance under load changes. Built for industrial-grade use, the SDCS-FEX-2A provides robust electrical isolation, high-speed feedback processing, and seamless compatibility with ABB’s DC drive ecosystem.
