the IS200HFPAG2ACB is a specific revision of the High-Frequency AC/Fan Power Supply Board (HFPA) used in the GE Speedtronic Mark VI turbine control system.
It is a critical component that manages power conversion and distribution within the control rack.
⚙️ Function and Key Specifications
The primary function of the IS200HFPAG2ACB is to act as a power supply for the other electronic boards and cooling fans within the Mark VI cabinet.
-
Power Conversion: It takes an input AC or DC voltage (e.g., from the DC link or an isolated 230 VAC source) and converts it into the precise, regulated, high-frequency square wave output voltages needed by the control circuitry.
-
Voltage Outputs: It typically provides regulated AC/DC outputs such as 17 V and 48 V (or 52 V) to power the other control boards and the system cooling fans.
-
Design: As a printed circuit board (PCB), it features:
-
Two Transformers and Heat Sinks for power conversion and thermal management.
-
Four Fuses and a Metal Oxide Varistor (MOV) for circuit protection.
-
Input/Output: It uses four stab-on connectors for power input and eight plug connectors for distributing the output voltages.
-
Diagnostics: Two LED indicators (DS1 and DS2) are included to provide a visual status of the output voltages (e.g., DS1 for the 17V line and DS2 for the 48V/52V line).
-
-
Loading: The total output loading of this series of board (IS200HFPAG2A) generally should not exceed 90 VA.
The “G2A” in the part number indicates the functional variant (Group 2 Assembly), and the “CB” suffix denotes a specific revision of that assembly, which has no configurable hardware and typically requires replacement or repair when faulty.
