380V four-wire three-phase, three-phase AC ammeter, RN7302 power collection chip, STC8A MCU, USB serial communication, communication isolation, safety status indication;
It is in testing status , and MCU program files are not provided yet. The low-voltage side uses dual type-C power supply;
High voltage is dangerous. This project does not bear any responsibility for the health and life safety of secondary developers or users of this project & does not guarantee any safety in the {schematic diagram: low-voltage non-isolated side, high-voltage side} area!
It is forbidden to connect the N terminal to the phase wire/live wire, otherwise danger will definitely occur!
