Description
Core Product Summary (Brand / Model / Key Attributes)
The GE DS200DCFBG1BGB is a DC Feedback Power Supply Board (functional acronym DCFB) manufactured by General Electric for the Mark V series and related drive platforms. It supplies control-level power to the drive and 115 VAC power to enclosure fans.
The board is used in AC2000, CB2000, DC2000, FC2000, ME2000, and EX2000 systems. It accepts input voltages in the range of 38–115 VAC from a control power transformer and incorporates circuits for control-level supplies, motor field power, driver stages for SCR gate pulse generators, and AC/DC signal monitoring. Configuration is performed via on-board jumpers and DIP switches. Diagnostic indication is provided by LEDs and a neon lamp for fuse status. The associated instruction manual is GEI-100028.

Detailed Product Overview
The GE DS200DCFBG1BGB is a power supply and feedback board designed for GE industrial drive and excitation systems based on the Mark V architecture. When installed, it receives AC power (typically 38–115 VAC) from the control power transformer and generates the regulated control-level voltages required by the drive electronics. It also supplies 115 VAC to enclosure cooling fans.
In addition to power distribution, the board contains circuits that process motor-related feedback signals, including armature current and voltage, motor field current, and AC line current. It provides driver circuits for the SCR gate pulse generators used in the motor field power path. An analog representation of motor voltage is made available for communication with the SDCC or LDCC control boards.
Configuration options are set by twelve jumpers (or thirteen on certain later revisions) and seven DIP switches. Three protective fuses safeguard the power circuits; their status is indicated by two LEDs and one neon lamp. Five test points allow measurement of key voltages and signals during commissioning or troubleshooting.
The board is intended for use only in the compatible GE drive families listed above. In EX2000 applications the functional role differs slightly from its use in the pure drive platforms. Installation, jumper settings, and any maintenance must follow the procedures given in GEI-100028 and the system-level documentation for the host drive.
