From the project
Isolated Multi-Rail Power Supply Monitor Capstone
Repository: PSMonitor Author:** Mike Capotosto
The Multi-Rail Isolated Power Supply Monitoring System measures the voltage and current of up to six floating power-supply rails while preserving galvanic isolation between measurement channels. Each rail is monitored by an LTC2945 power monitor connected through an isolated I²C interface to an Arduino GIGA R1 WiFi. The Arduino firmware performs data acquisition, engineering-unit conversion, alarm evaluation, persistent configuration storage, local display control, HTTP service, and Ethernet communication with an EPICS Input/Output Controller.…
