About the IC3600EPZU1A
The IC3600EPZU1A is a Power Supply Board designed by GE for either the Mark I or the Mark II series. The first of the Speedtronic gas/steam turbine management systems, the MKI was introduced in 1969. The MKII was introduced a few years later in 1973. Both series now have millions of hours of accumulated use managing systems large and small. Both series are designed to be scalable and adaptable to the needs of the user and can manage systems as small as 4000 hp to as large as 400 Mw (combined cycles.)
The IC3600EPZU1A is a FANUC component. It has several markings on the front of the board, including the GE ‘U.S.A.’ logo, the codes 006/01 and 002/01, the board identification, and the mark “EPZU.” One board edge has been numbered.
The IC3600EPZU1A is built with four diodes, one fuse and two wire wound resistors, which are marked 2147901 1K 5%10W and 214902 10K 5% 10W. The board has capacitors made of polyester vinyl (2Q78 10μF +/- 10%,) and three lines of three aluminum electrolytic capacitors (30D + TE 1307 50μF 50 VDC 105C + 9807H.) The last component on the board is a metal oxide varistor, marked MOV1. Varistors are mainly used to perform as a line voltage surge suppressor. Spikes are shorted through the device within nanoseconds.
The IC3600EPZU1A is built with twenty-five pins on one edge. These pins connect to wiring within the main Speedtronic frame which allows the board to communicate with the rest of the system.
