The IS2020RKPSG1A developed by General Electric is a Mark VI Module component. The Mark VI was created as a gas and steam turbine management systems. This board is a self-contained Module designed with a front faceplate that is labeled along its top edge with the words âPower Supplyâ and three LED indicators that are labeled normal, fault and available providing the user with an at glance view to the status of the board. There is a toggle switch that is the only user control in this Module providing front-panel control of Power Supply output voltages and when toggled serves as a fault reset. Faults occurring within this Module will result in output shutdown and will require a reset action to clear. In the event of a permanent failure, a replacement of the entire Power Supply is required. This Module is equipped with 125 V dc input voltage and 400 W output rating. Outputs include five +28V outputs, three +28V remote outputs as well as a single PS335 output. To prevent electric shock power must be turned off to the Module before touching it or any connected circuits. Do not insert, remove, or adjust connections will power is in.
