GE IS200ISRJG1A IS200ISRJG1AAA Rack Power Supply Board

The IS200ISRJG1A IS200ISRJG1AAA functions as a rack power supply board for turbine systems. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200ISRJG1A serves as the standard version for rack power distribution. Its variant, the IS200ISRJG1AAA, includes a conformal coating for enhanced circuit protection. Both boards supply regulated power to VME rack modules for steam and gas turbine controls.

Core Technical Specifications

This board provides multiple DC voltage outputs for rack module operation. You will also find built-in overvoltage protection on each output channel. The board stores minimal energy but uses capacitors for voltage regulation. Meanwhile, the backplane connector distributes power to all rack slots.
