Product Overview

The GE DS200DCFBG1BLC is a DC Feedback Power Supply Board developed for GE’s Mark V Turbine Control System Series, specifically designed to deliver control-level power to the system and auxiliary components. This module also provides power to the drive enclosure fan and is compatible with various GE exciter and drive series, including DC2000, AC2000, CB2000, ME2000, and FC2000.

Compared to its base model, DS200DCFBG1, the DS200DCFBG1BLC includes three key functional revisions, enhancing its reliability and functionality in demanding environments such as gas, steam, and wind turbine automation systems.

Key Features

• Input Range: Accepts AC inputs from 38 to 115 VAC

• Input Frequency: Supports frequencies from 0 to 500 kHz, depending on voltage

• Output Function: Supplies control-level system power and powers the enclosure fan

• Compatibility: Usable across various GE exciter and drive series

• Configurable Components:

• 12 jumpers

• 7 DIP switches

• Visual Diagnostics:

• 2 LED indicators

• 1 neon lamp

• Overcurrent Protection:

• 3 onboard protective fuses

Circuitry Components

The DS200DCFBG1BLC board integrates several key internal circuits, including:

• AC and DC monitoring circuit

• Control-level power supply circuit

• Motor field power circuit

• Driver circuit

These provide stable and regulated power across system components and aid in fault diagnostics and protection.

Test Points

Five onboard test points allow for routine monitoring and diagnostic checks:

These test points are clearly labeled on the PCB and provide essential reference voltages to ensure reliable operation and easy troubleshooting.

Applications

The DS200DCFBG1BLC is integral to the Mark V Turbine Control System, widely used in:

• Gas Turbine Systems

• Steam Turbine Systems

• Wind Turbine Systems

• Automated Drive Assemblies
