About the IC3600EPZU1D
The IC3600EPZU1D is a component for the Mark I/ Mark II Speedtronic series from GE. These systems used solid state and integrated circuits for logic and computation functions to improve performance and reliability. Both systems were designed by General Electric to perform several tasks, including controlling the turbine output power and keeping that power to within the unit’s capability, performing start-up sequencing in the turbine and its auxiliaries, providing a protective shutdown of the turbine if a non-recoverable event occurs anywhere within the turbine, the control system or its auxiliaries, and monitoring and annunciating malfunctions within these systems.
The IC3600EPZU1D acts as a Power Supply card and carries several markings and codes. These include the GE trademark, the unique board identification number, the marks “EPZU” and “PDA,” and the codes 006/01 and 002/01. One edge is numbered 1/5/15/25/35/45/51. This edge has twenty-five metal pins fitted to it. These pins are connected by wiring into the larger system, and allow communication to occur between the board and the rest of the system.
The IC3600EPZU1D is built with two wire-wound resistors. These are both marked with their resistance. The board has five diodes and one fuse. It is built with one polyester vinyl capacitor and nine capacitors made of aluminum electrolytic material. Each of these components is marked with its capacitance. The board has one component marked MOV1. This denotes a metal oxide varistor or voltage-dependent resistor. These devices are used as a line voltage surge suppressor and can protect from transient voltages.
