The IS2020RKPSG1A is a module component manufactured by GE for the Mark VI. Created for steam or gas turbine management, the Mark VI was one of the last of the Speedtronic systems distributed by General Electric.
The IS2020RKPSG1A is a self-contained VME rack power supply module. The front faceplate of this module is marked “Power Supply.” The faceplate has an open (waffled) area to allow air movement into the component. It has three locations at the bottom of the faceplate for recording the GE catalog number, the revision number, and the serial number. This part of the module also includes three LED indicators (green, red, and yellow) as well as a single toggle switch. This switch is the only user control on the module. This toggle switch can be toggled to reset faults. These faults fall into three categories: those that require a reset action to clear, those that result in an output shutdown, and those that result in permanent failure of the power supply. This module has a 400 W output rating and a 125 Vdc input voltage. It has nine outputs, including three +28V remote outputs, a single PS335 output, and five +28V outputs.
The IS2020RKPSG1A has a fan as part of its design. However, the fan is only used when the module is mounted into the rack position. This fan is powered from the top connector.
