IC3600EPZU1

IC3600EPZU1 is a Power Supply Board developed by GE. These were the first two Speedtronic gas/steam turbine management controllers. They're both meant to limit turbine output to within the unit's capabilities, sequence parameters during startup, provide a precautionary shutdown in the event of a non-recoverable system failure, and monitor and annunciate problems.

• It is designated EPZU separately from its board identification number and has the identifiers 006/01 and 002/01. One of the edges has a number. One fuse, four diodes, and two wire wound resistors make up the IC3600EPZU1. 2147902 10K 5% 10W and 2147901 1K 5% 10W are the model numbers.
• It has one polyester vinyl capacitor with the markings 2Q78 10F +/- 10%. Nine aluminum electrolytic capacitors are arranged in three lines of three. 30D + TE 1307 50F 50 VDC 105C + 9807H are the markings on these.
• There is also one metal oxide varistor on the board, which is labelled MOV1 and is located in the middle of the board. Varistors are voltage-dependent resistors with diode-like voltage-current properties.
• They are employed to safeguard electrical devices against high transient voltages, and when a strong current is produced owing to high voltage, they will short themselves out.
• On one edge of the IC3600EPZU1, there are twenty-five pins. These pins are linked together when the IC3600EPZU1 is installed into a Speedtronic frame, allowing the board to interface with the rest of the system.
