About the IC3600TPSF1A
The IC3600TPSF1A is a board component for the first Speedtronic series from GE, the Mark I. It can also fit as a component for the Mark II. These series were developed by GE for the management of gas and steam turbines, with a focus on improving the reliability and efficiency of these systems regardless of their size or complexity. To that end, the MKI and MKII are adaptable and scalable and have multiple configurations to allow for the proper management of everything from unmanned single turbine systems to full power plants. Both systems have been in use for over four decades and have long been replaced by other Speedtronic systems like the MKIV, MKV, MKVI, and MKVIe. And although GE considers the MKI and MKII obsolete because of this, both systems continue in active use.
The most notable component on the IC3600TPSF1A is a power transistor fitted into a large heat sink. This heat sink is attached to the board via three screw mounts. The transistor fits into the center of this heatsink and is connected by two screw-mount poles. One pole is connected to the board via surface mounted wiring. The board makes use of eight smaller transistors of four different designs.
The IC3600TPSF1A uses one trim potentiometer. It has three capacitors made of aluminum electrolytic material. These are marked C1, C2, and C3. C4 is made of a different material. The board uses carbon composite resistors mounted vertically and horizontally. Diodes tend to be mounted horizontally.
The IC3600TPSF1A is marked with the codes 68A999198G1 and ROM. One edge is numbered and populated with right-angled pins.
