Description
The GE DS200DCFBG2B DC Feedback Power Supply Board is a key component in the Mark V Control System, designed to deliver regulated and isolated DC voltages for drive control and armature current feedback circuits. It receives 38 V ac from the CPT and converts it into multiple DC outputs including ±24 V, ±15 V, and +5 V, each tailored for specific control and feedback functions. Integrated fuse protection and LED indicators ensure safe operation and simplified diagnostics.
