About the DS200DCFBG2BNC

The DS200DCFBG2BNC is a Power Supply Board designed for GE’s Mark V system.  The Mark V is a version of GE’s Speedtronic gas and steam turbine management system, which has seen continuous development since the late 1960s.

The DS200DCFBG2BNC is a revised version;  the original device for this functionality was the DS200DCFBG2 parent Power Supply Board, which lacks the three significant product revisions found in the DS200DCFBG2BNC.
