About the IS200HFPAG1A

The IS200HFPAG1A is a PCB component designed by GE for the Mark VI gas and steam turbine control system.  The Mark VI is part of the Speedtronic line that has been under development by General Electric since the release of the first Mark I system in the late 1960s.  Each Speedtronic system is designed to improve the reliability of GE’s heavy duty turbines. The Mark VI is built with a PC operator interface running on a Windows platform.

The IS200HFPAG1A functions as an AC/Fan Power Supply for High-Frequency applications.  The board receives input voltages (AC or DC) and converts the input into the needed output.  This may be a 48 VAC, a 52 VAC, a 48 VDC, or a 17.7 VAC output. The output for the board (total) should not exceed 90VA.  The IS200HFPAG1A is a multi-purpose board that may be mounted in various drive cabinets. It is usually mounted near a board rack or a fan enclosure.

The IS200HFPAG1A is built with four stab-on input connectors and eight output plug connectors.   The board has a metal oxide varistor and four fuses to protect circuitry. There are two LEDs (light emitting diodes) located on the board to indicate the status of voltage outputs.   The board has two heat sinks, two transformers, three high-voltage capacitors, and several transistors. Resistors tend to be of metal film material, but other materials are used. The board has capacitors of polyester vinyl and of ceramic material.  More information on the board components and their functions can be found in GE publication GEI-100255.
