GE DS200DCFBG1BLC
Product Name: DS200DCFBG1B Variant “LC” (Coated, Rev B/C, Excitation-Optimized)
Product Brief: Same functional family as DCFBG1B but with conformal coating (L), revised circuit (C), optimized for generator excitation feedback.
Technical Specifications
-
Derived from DCFBG1B: +5/±15/±24 V, field supply, SCR drive
Detailed content
-
Enhancement: Rotor DC voltage/current sensing for AVR loop
-
Coating: Polyurethane conformal (humidity/salt mist resistant)
-
Protection: Over/under excitation hardware limit
-
Temp: –40 °C to +85 °CFunctional Features: Closed-loop excitation correction, surge-tolerant components.Working Principle: Supplies control power and feeds excitation regulator with real-time rotor measurements; clips field demand on limits.Application: Generator AVR, hydro/steam exciters, retrofit of DCFBG1B in coastal plants.Installation & Notes: Do not remove coating for inspection; verify B/L/C revision compatibility with existing rack BOM.
