Product Overview
JSY-MK-163 single mutual inductance electric energy metering module is a highly integrated measurement and digital communication technology, which can complete single-phase AC parameter measurement of electric energy measurement, collection and transmission, and can accurately measure single-phase AC voltage, current, power, and power factor, frequency, power and other electrical parameters. With 1 TTL level interface, small size, simple interface, and excellent cost performance.
In particular, the complete electrical isolation circuit is adopted, which solves the safety problem of not being isolated from strong electricity in cross-industry applications, and can be easily embedded in various devices that need to measure power consumption.
The single mutual inductance electric energy metering module can be widely used in energy-saving renovation, electric power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries to monitor the current and power consumption of AC equipment.
