Isolated DC current shunt current sensor, Detection range 0-100A, working voltage DC 5V

This module is used to measure and monitor current consumption by utilizing a external shunt resistor. If the current exceeds a preset value, the relay on the module is activated. Uses include building automation and facility mangement systmes where acquiring information on energy usage can lead to increased efficiency. They can also detect equipment issues and help prevent damage by detecting over-current and/or short-circuit conditions.
