Product Description P/N: 3ADT311500R1
Description
The ABB 3ADT311500R1 is an SDCS-FEX-2A field exciter board for compatible DCS-series DC drives. It converts a single-phase AC supply into controlled DC excitation for the motor field winding. The board supports field-current regulation as part of the drive’s motor-control system.

Information About 3ADT311500R1
The 3ADT311500R1 is associated with the SDCS-FEX-2A hardware documented for ABB DCS500B and DCS600 installations. Its assembly combines power semiconductors with digital control circuitry. The power stage uses diode and thyristor modules arranged as a half-controlled bridge. Installation is internal to the compatible armature converter, with the permitted configuration determined by the converter frame and field-current requirements.
Key Features:
- Field Excitation: Supplies controlled DC current to the field winding of a compatible DC motor.
- Single-Phase Input: Accepts a nominal AC supply within the documented 110–500 V range.
- Controlled Rectification: Uses a half-controlled bridge with diode and thyristor power components.
- Digital Regulation: Generates firing pulses through onboard digital control circuitry.
- Field Current Capacity: Supports up to 16 A, subject to the installed converter rating.
- Internal Installation: Mounts within compatible DCS converter assemblies.
- Drive Coordination: Exchanges control information with the associated drive electronics.
The 3ADT311500R1 delivers the reliability and precision required for regulated field excitation in industrial DC motor-drive systems.
