About the 193X711AEG03

The 193X711AEG03 is a Power Amplifier Card manufactured by GE for their DC Drive systems, including the SCR Drive and the Speed Variator Drive.

The 193X711AEG03 is built with a front identification panel designed to allow for easy insertion and removal of the board from the rack.  This silver and blue panel has a rounded handle connected about halfway down its front surface. The board has one round opening cut just above the handle, which is labeled “P206.” This opening lines up with a trim potentiometer located on the surface of the printed circuit board. The front panel includes the board’s id number, its use (+ Power Amplifier,) and the GE logo.  

The 193X711AEG03 is built with a single coil inductor.  This component is connected to the board using a screw mount.  The board has two large and two small transformers, all in frame mounts.  One of the large transformers is marked 04X156DA008. The board uses electrolytic and polyester vinyl capacitors. One polyester vinyl capacitor is mounted together with a small bulb between two metal posts. The board uses carbon composite resistors and wire wound resistors. The wire wound resistors are mounted on brackets above the board. CCRs may be mounted to the board vertically or horizontally.

The bottom surface of the 193X711AEG03 has a large heat sink attached.  This is marked 769B767EAG02. The heat sink has four screw connections. Two of these connect to surface wires that thread through holes in the PCB from the top side of the board.  Many surface wires are used on the 193X711AEG03 to connect components to each other or to the board. In the case of board connections, metal wire-to-board connections have been used.  If the board begins to have sporadic issues, these connections need to be checked for proper contact.
