SBX Power Board

Figure 1

The power board of each SBX is an all-in-one, point-of-load power system for detectors and the SBX. It powers the entire system from a single 48VDC input by generating all voltages for slope box, preamp, pickoff board and Raspberry Pi. Furthermore, it allows a single detector and its SBX to be run entirely from one PoE (power over ethernet) port, enabling standalone detector operation. It is located on top of the pickoff card inside the SBX.

Figure 1 shows how the Power Over Ethernet compliant allows a single detector plus SBX to be run entirely from one PoE port, enabling standalone detector operation. The Ethernet cable is plugged into the power board inside the SBX, and is used to power the slope box and pickoff, and preamp. An IOC within the SBX transfers signals to the digitizer, giving each detector the ability to run self-sufficiently. Furthermore, the Ethernet cable enables the user to view indicator values and control certain process variables using EPICS, which helps curate and monitor the data received.

EDM Interface for Power Board

The power board of the SBX has the capability to control and indicate various process variables via EDM. Figure 2 shows what the screen looks like. There are display values for temperature, power, and fan speed, and controls for power status and writing port data.
