GE Mark VI IS200HFPAG1AEC High Frequency Board

الوصف

The IS200HFPAG1AEC is a High-Frequency AC/Fan Power Supply Board (HFPA) designed by General Electric (GE) for use in their Speedtronic Mark VI series of gas and steam turbine control systems.

Its primary role is to ensure the control system components receive stable, regulated power.

⚡ Key Functions and Specifications

• Function: It acts as a power converter, taking incoming AC or DC input voltages (including isolated 230 VAC or DC link inputs) and converting them into the regulated output voltages necessary to power other boards, such as the I/O processors and fans, within the Mark VI rack.

• Output Voltages: Common outputs from this type of board include:

  • 48 VDC

  • 48 VAC square wave

  • 17.7 VAC square wave (often for power circuitry)

• Design: The board is built with two transformers, heat sinks, and multiple components like diodes, resistors, and capacitors. It typically has four stab-on connectors for input power and eight plug connectors for output voltages.

• Diagnostics: The board includes LED indicators (often labeled DS1 and DS2) to signal the status of its output voltages, allowing for basic diagnostics.

• Revision: The “AEC” in the part number indicates a specific revision or configuration of the base IS200HFPAG1A board. It is functionally similar to other revisions like G1ADC or G1ADB, all of which fall under the same High-Frequency Power Supply category.

The board is a critical part of the control power architecture for the Mark VI system, which manages and protects heavy-duty gas and steam turbines.
