RFSSASwPS is a switched power supply for the active electronic components with a relay for AC-to-DC converter remote control of the Solid State Amplifier (SSA) Tower.

General description

RFSSASwPS is a 6-channel power supply that provides ground (GND), PE (Protective Earth), -12V(1A), +5V(12A), and +12V(5A) DC voltages from one 132W AC-to-DC converter. It includes a Beagle Bone Black that works as a digitizer for the DC signal from the voltage and current consumption sensor and EPICS IOC (Input/Output Controller) server to provide these measurements for high-level application through PVs (Process Variables). The simplified diagram with the main components and ports is shown in Fig. 1.
