Product Description

The SDCS-FEX-4 is a compact, internal field exciter module that is typically mounted directly within the drive cabinet or on the control assembly. It converts AC supply voltage into a regulated DC current for the motor field. This specific model is part of the “FEX-4” series, which is known for its reliability in demanding industrial environments and its ability to provide high-resolution current regulation for optimized motor performance.

Technical Specifications

Product Advantages

• Seamless Integration: Designed specifically for ABB DCS800 and DCS550 series, ensuring plug-and-play compatibility and simplified parameter settings.

• Precise Field Weakening: Enables the DC motor to operate above its base speed by accurately reducing field current, which is critical for high-speed industrial applications.

• Compact Footprint: The high power density of the board allows it to be installed inside the drive housing, saving valuable space in the electrical control cabinet.

• Advanced Diagnostics: When paired with the DCS800 control system, it provides real-time feedback on field current and voltage, allowing for predictive maintenance.

• High Reliability: Built with industrial-grade components to withstand voltage fluctuations and harsh thermal conditions common in heavy industry.

Precautions

• High Voltage Hazard: The board operates with high AC and DC voltages. Ensure all power is disconnected and discharged for at least 5 minutes before handling or servicing.

• Firmware Matching: Ensure that the drive’s firmware supports the SDCS-FEX-4 module to avoid communication errors or “Field Loss” trips.

• Thermal Management: Do not block the airflow around the board. Overheating can lead to current derating or permanent damage to the power semiconductors.

• Electrostatic Discharge (ESD): Use proper grounding straps when handling the board, as the sensitive control electronics can be damaged by static electricity.

Product Applications

The SDCS-FEX-4 is utilized in a variety of heavy-duty DC motor applications, including:

• Metals Industry: Controlling the field excitation for motors in rolling mills, wire drawing machines, and coilers.

• Pulp and Paper: Used in paper machine drives where precise speed synchronization across different sections is required.

• Mining and Material Handling: Managing the torque and speed of large mine hoists, conveyors, and excavators.

• Plastic and Rubber: Driving extruders and mixers that require high starting torque and stable running speeds.
