الوصف
The GE DS200TCPSG1AHC is a specific part number for a DC Input Power Supply Board (functional acronym TCPS) manufactured by General Electric (GE).
This circuit board is a core component of the GE Speedtronic Mark V Turbine Control System, which is used for the automated control and protection of gas, steam, and wind turbines.1
⚙️ Primary Function and System Role
The primary role of the DS200TCPSG1AHC board is to convert and regulate the incoming DC power for distribution throughout the control system.
- Input: It receives bulk 2$125 \text{ VDC}$ power from the main power distribution board (TCPD) within the Mark V panel.3
- Output: It transforms this bulk input into the various stable, regulated DC voltages required by the other electronic components and I/O boards in the system.4
- Distribution: It is crucial for supplying power to essential circuits, including:
- Microprocessors and digital logic circuits (typically 5$+5 \text{ VDC}$).6
- RTD (Resistance Temperature Detector) power supplies.
- Servo valve current outputs for hydraulic actuation.
- mA output power for analog signals.7
It is typically located in the R (Control) and I/O cores of the Mark V system panel.8
📋 Technical Specifications (General TCPS Board)
