Introduction

LLRFLinPS is a linear power supply for the active RF components of the LLRF system.

General description

LLRFLinPS is a 6-channel power supply that provides ground (GND), PE (Protective Earth), -5V(0.7A), +3.3V (if needed with extra electronics), +5V(6A), and +12V(1.7A) DC voltages from one 75W 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.
