Product Short Description
Product Introduction
The GE DS200DCFBG1BGB is a specialized DC Feedback Power Board (DCFB) tailored for GE Mark V Speedtronic control systems and a wide array of GE drive control platforms, such as AC2000, CB2000, DC2000, FC2000, ME2000, and EX2000. It serves as a core power supply and feedback management hub, generating and regulating 24 VDC control-level power for DC drives or exciters, and delivering 115 VAC power to enclosure fans. The board integrates motor field power circuits, driver circuits, AC/DC monitoring circuits, and control-level power supply circuits, and communicates with SDCC/LDCC control boards to monitor and adjust motor voltage feedback signals, which are converted to frequency signals for controller processing. It comes with 12 configurable jumpers, 7 DIP switches, 3 protective fuses, 5 test points, and multiple connectors for seamless integration, and is supported by the GEI-100028 reference manual. It is built with industrial-grade components to ensure consistent performance in harsh industrial environments, serving as a critical power and feedback control hub in turbine and heavy-duty drive systems.
