GE DS200DCFBG1B DS200DCFBG1BNC Power Supply Board

Key Technical Specifications

This GE DS200DCFBG1B DS200DCFBG1BNC board accepts 125V DC nominal input voltage. It delivers 8A total output current across four regulated DC rails. The unit measures 26 cm in length, 18 cm in width, and 5 cm in height. Its total weight reaches 1.1 kg without any packaging materials.

The GE DS200DCFBG1B DS200DCFBG1BNC includes four isolated output channels for system distribution. Additionally, it features one input fuse holder for overcurrent protection. A single 6-pin terminal block connects the main DC input. The board contains 1 DC-DC converter, 4 rectifiers, 6 voltage regulators, 10 capacitors, and 18 resistors.

Energy Storage	1500 µF at 200V

GE DS200DCFBG1B DS200DCFBG1BNC stores energy using two parallel electrolytic capacitors. Together, they provide 1500 µF at 200V rating for input hold-up. This energy storage maintains all outputs during 40 millisecond input interruptions. Therefore, the board keeps critical controls operational through short battery sags.

Design and Integration

Both the GE DS200DCFBG1B and DS200DCFBG1BNC versions share identical power topology. These boards use four-layer PCB construction with heavy copper for high current paths. Consequently, the GE DS200DCFBG1B DS200DCFBG1BNC operates reliably from -20°C to +55°C ambient temperature.

For installation, you need M4 screws for the four mounting holes. The board draws 6.5A typical input current at full load. Each output includes short-circuit and overcurrent protection. We recommend using 12 AWG wire for the DC input connection.

Practical Application

This power supply board converts 125V station battery power into multiple logic voltages. It feeds processor boards, I/O modules, and communication interfaces in a control rack. The GE DS200DCFBG1B DS200DCFBG1BNC also provides power good signals for each output rail. Therefore, it serves as the main power source for GE drive and turbine control systems.
