The GE IS200HFPAG1ADC is a High-Frequency AC/Fan Power Supply Board (HFPA), which is a crucial component of the General Electric Mark VI Speedtronic Turbine Control System.1
Its primary function is to serve as a power converter, taking a high-voltage input (AC or DC) and regulating it to supply the necessary low-voltage AC and DC power required to operate essential equipment like cooling fans and isolated power circuitry within the turbine control cabinet.2
⚙️ Key Technical Details
The board belongs to the $\text{HFPAG1A}$ series, where the $\text{ADC}$ suffix denotes a specific revision of the hardware/firmware, but its core function remains consistent with other versions in the family.
| Feature | Detail |
| System | GE Mark VI Speedtronic Turbine Control (used in gas and steam turbine management) |
| Functional Role | Converts and regulates power for cooling and isolated control circuits. |
| Input Connectivity | Features four stab-on connectors for receiving both AC and DC input sources. |
| Output Connectivity | Equipped with eight plug connectors for distributing the converted output voltages. |
| Primary Outputs | 48 VDC, 48 VAC (Squarewave), and 17.7 VAC (Squarewave, typically at 25 kHz) for isolated power circuitry. |
| Protection | Includes four fuses and typically a Metal Oxide Varistor (MOV) for surge and overcurrent protection. |
| Diagnostics | Has two LED indicators (DS1 and DS2) to monitor the status of the key output voltages (e.g., 17.7 VAC and 48 V outputs). |
The board is essential for thermal management and providing electrically isolated power, ensuring the reliable and continuous operation of the sensitive control electronics in the Mark VI system.
