The board efficiently converts the single 125VDC input into multiple required output voltages. It distributes these voltages to different functional modules through connectors like JC, JP1, and JP2 in a daisy-chain or targeted way. This function ensures that each component in the turbine control system, from high-power servo valves to sensitive microprocessors, receives the exact voltage it needs for operation.
The three dedicated fuses on the board form a first-line protection barrier for the circuit. When irregular or excessive current flows through the board due to short circuits or component failures, the fuses trigger and shut down the corresponding circuits promptly. This prevents damage to the board itself and avoids cascading damage to expensive core components connected to it.
The multiple test points on the board enable straightforward troubleshooting. When the system power supply malfunctions, technicians can directly measure electrical parameters at these test points without disassembling the entire system. This approach shortens the time spent identifying issues such as poor contact, fuse burnout, or voltage loss, and improves the efficiency of maintenance work.
It achieves seamless integration with the Mark V system without the need for additional hardware modifications or software programming. Its standardized voltage output and connector design ensure consistent compatibility with various functional boards in the system. The plug-and-play design allows technicians to quickly replace faulty boards, minimizing downtime for the turbine control system.
It is widely used in the Mark V control systems of gas and steam turbines in thermal power plants. It provides stable power for turbine speed sensors, fuel valve control modules, and exhaust temperature monitoring components. Stable voltage output ensures accurate execution of turbine start-stop, load adjustment, and emergency shutdown commands, which is critical for maintaining continuous power generation.
In petrochemical refineries, many compressors and transfer pumps are driven by steam turbines controlled by the Mark V system. This board supplies power to the turbine’s pressure control valves and flow sensors. It maintains stable operation even in harsh environments with high humidity and flammable gas, ensuring the safety and continuity of oil and gas compression and transportation processes.
Mining sites use turbines to power large ventilation equipment and conveyor systems. The DS200TCPSG1A board is integrated into the supporting Mark V control systems. It converts and distributes power to ensure the stable operation of turbine control components under harsh conditions such as large vibration and heavy dust, preventing production interruptions caused by power supply failures.
Many metallurgical plants still rely on legacy Mark V turbine control systems to power blast furnaces and smelting equipment. This board serves as a key spare part. When the original power supply board fails, replacing it with the DS200TCPSG1A can quickly restore the power supply of the control system, reducing downtime and avoiding losses caused by interrupted smelting processes.
Offshore oil and gas platforms use turbines for power generation and equipment driving. The board adapts to the marine environment with high salt spray and humidity. It provides stable multi-voltage power for the Mark V-based turbine control system, ensuring reliable transmission of emergency shutdown signals and speed control signals. This protects the safety of offshore equipment and operators.
