Core Function

DS200DCFBG1BJB DCFB power feedback board is the core power supply hardware for GE Mark V and EX2000 excitation system. It converts AC input into multi‑channel stabilized DC control power for drive controllers and I/O boards, meanwhile supplying 115VAC power for cabinet cooling fan. DIP switches and jumpers support on‑site parameter configuration. Fuse and indicator circuits realize power fault monitoring. It provides reliable power guarantee for excitation drive unit, ensures stable operation of turbine excitation system under complex power‑plant working conditions.

Product Details

DS200DCFBG1BJB belongs to DCFB series power feedback board of GE Speedtronic Mark V / EX2000 excitation control system.

This rack‑mount multilayer PCB board is installed inside EX2000 excitation cabinet. It undertakes AC‑DC conversion and power distribution work for the whole drive control unit. Multiple DIP switches and jumpers facilitate field adjustment for different operating conditions. On‑board fuse components offer over‑current protection for each power output branch, LED and neon lamp directly display fuse failure status for quick maintenance. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power‑plant excitation cabinet. Widely deployed in gas‑steam turbine generator EX2000 excitation system for control power supply and power signal monitoring.

It belongs to critical power supply spare‑part for EX2000 excitation system, widely used in overhaul and renovation projects of power generation units. It is important spare hardware for power loop debugging and defective DS200DCFBG1BJB board replacement.
