Features:
- Converts 125V DC input into +5V, +24V, ±15V, and ±24V regulated outputs; powers RTD conditioners, servo drivers, and microprocessors
- No hardware jumpers or software settings; install and power on; board operates immediately
- Three replaceable fuses (overcurrent), MOVs (surge suppression), heat sinks (thermal management), and test points (voltage verification)
The DS200TCPSG1AME is a specialized power supply board for GE’s Mark V turbine control system. Its primary function is to convert raw 125V DC field power (supplied by the TCPD board) into the multiple regulated DC voltages required by various Mark V components . It outputs +5V DC for microprocessor logic, +24V DC for I/O and relay circuits, and ±15V DC and ±24V DC for analog circuits and servo valve drivers . These outputs are distributed via dedicated connectors (2PL, JC, JP1, JP2) to boards such as the TCQC (servo control), TCCA (analog I/O), and TCDA (digital I/O) . By providing clean, isolated, and regulated power to these critical boards, the DS200TCPSG1AME ensures stable operation of turbine protection logic (e.g., overspeed detection, exhaust temperature monitoring) and precise actuator control.
The DS200TCPSG1AME is designed for simplicity and reliability. Unlike many industrial electronics that require configuration via DIP switches, jumpers, or software, this board has no configurable elements . It is a true "install and operate" module. The technician inserts it into the designated slot in the Mark V
core, connects the 125V DC input via the J1 connector, and the board immediately begins converting and distributing power . This no-configuration design eliminates the risk of human error during setup, such as setting an incorrect jumper position or uploading wrong parameters.
The DS200TCPSG1AME is engineered to survive harsh industrial environments and protect downstream components. It includes three user-replaceable fuses (125V DC rated) that provide overcurrent protection on critical output circuits . If a fault occurs (e.g., a short circuit on a servo valve output), the fuse opens, preventing damage to the power supply board and the connected load. The board also features metal oxide varistors (MOVs) for surge suppression, protecting against voltage spikes from lightning strikes or switching transients.
The DS200TCPSG1AME General Electric Power Supply Board may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).

- Power Generation: Used in GE heavy-duty Gas Turbines (Frame 5, 6, 7, and 9) and Steam Turbines to power the critical control cores (R, S, and T).
- Chemical & Petrochemical Processing: Connecting to pH, conductivity, and gas analyzers for reaction monitoring, with outputs driving modulating control valves for reagent dosing. Channel isolation prevents cross-contamination of signals from aggressive chemical environments.
- System-Wide Power Distribution: It converts the 125 VDC station battery (or main DC bus) input into regulated low-voltage DC outputs required for microprocessors, I/O boards, and sensitive field instrumentation.
- Power Input (125 VDC): Typically receives bulk DC power through heavy-duty plug connectors (often labeled 2PL) from the
(Power Distribution) core.
- Voltage Distribution: Distributes multi-rail DC power (e.g., +/- 5V, +/- 15V, and 24V) to neighboring boards like the TCQC (Common I/O) and TCCA (Control Architecture) through ribbon cables and high-density pin connectors (e.g., J1, J2).
- Onboard Test Points: Features physical test points on the front edge of the board, allowing technicians to use a multimeter to verify voltage stability without disconnecting the board.
- Redundancy Support: Designed to operate within a Triple Modular Redundant (TMR) architecture. Each of the three control cores (R, S, T) has its own TCPS board, ensuring that a single power supply failure does not cause a turbine trip.
- Electrical Isolation & Fusing: Equipped with multiple high-speed onboard fuses and Metal Oxide Varistors (MOVs) to protect downstream microprocessors from input surges, ground faults, and electromagnetic interference (EMI).
- Component Compliance: Built to meet GE’s internal Speedtronic standards for high-temperature resilience (up to 60°C) and vibration resistance common in power plant environments.
