GE DS200DCFBG1BJB DC Feedback Power Supply Board

The GE DS200DCFBG1BJB, also known as DCFB board, is a DC feedback power supply board designed for GE Mark V Speedtronic turbine control and 2000‑series drive systems. It converts AC input into multiple regulated DC voltages and collects power feedback signals for drive closed‑loop control.

This plug‑in rack PCB is equipped with DIP switches, fuses, LED indicators and multiple connectors. Original production has been discontinued. It is widely stocked as aftermarket spare parts for power plant turbine and heavy‑duty drive cabinet maintenance and retrofitting.
