GE DS200DCFBG1BLC DC Feedback Power Supply Board
The GE DS200DCFBG1BLC is a DC feedback power supply board (DCFB board) for GE Mark V Speedtronic turbine control systems and DS200 series drive racks. It converts alternating current into multiple groups of stable direct‑current power and collects voltage and current feedback signals for closed‑loop regulation.


This plug‑in printed circuit board is fitted with protective fuses, jumpers, test points and LED diagnostic lamps. Original production has been discontinued. It is widely supplied as aftermarket spare parts for overhaul and technical upgrading of power plant turbine control cabinets.
