GE IS200HFPAG2A Mark VI Fan/Transformer Card

الوصف

 the GE IS200HFPAG2A is a High-Frequency AC/Fan Power Supply Board (HFPA) used in the GE Speedtronic Mark VI series of gas and steam turbine control systems.¹

It’s often described as a Fan/Transformer Card because its primary functions are to manage cooling fans and regulate power via its internal transformers.²

⚡ Key Functions and Specifications

This board plays a crucial role in providing stable power to the control system components:³

• Power Conversion and Regulation: The IS200HFPAG2A receives either AC or DC input voltage (commonly 230 VAC) and converts it into the necessary regulated AC square wave output voltages required by other boards in the Mark VI rack.⁴

  • It typically outputs regulated voltages like 17.7 V AC and 48 V AC/DC.⁵

• Fan Management: The board is essential for powering and regulating the cooling fans, ensuring that critical electronic components within the control cabinet maintain an appropriate operating temperature (usually rated for an ambient range of ⁶$0^{\circ}C$ to ⁷$+60^{\circ}C$).⁸

• Design: It’s a printed circuit board (PCB) assembly that includes:

  • Two Transformers and Heat Sinks for power conversion and thermal management.⁹

  • Four Stab-On Connectors for voltage input.¹⁰

  • Eight Plug Connectors for voltage output.¹¹

  • Four Fuses and a Metal Oxide Varistor (MOV) for circuit protection.¹²

  • Two Status LEDs (DS1 and DS2) that indicate the status of the output voltages (e.g., 17V and 48V outputs).¹³

The board is a key component in the power architecture of the Mark VI system, which is a highly reliable control platform for industrial turbines.¹⁴
