Embedded AC Single Phase Power Metering Module Moudbus TTL Electricity Energy Metering PCBA
JSY-MK-1003F is a single-phase mutual inductance power metering module that can measure, capture and transmit electrical parameters. It can accurately measure single-phase AC voltage, current, power, power factor, frequency, electricity and other electrical parameters. With 1-channel TTL level interface, fully isolated circuit, small size, simple interface, and can be easily embedded in various devices that need to measure electricity consumption, with excellent cost-effectiveness.
JSY-MK-1003F can be widely used in energy-saving renovation, power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries to monitor the current and power consumption of AC equipment.
Features:
1. Capture single-phase AC electrical parameters such as voltage, current, power, factor, frequency, and energy etc.
2. Using dedicated measurement chips and effective value measuring methods, with high measurement accuracy.
3. With TTL communication interface, 3.3V interface.
4. Modbus-RTU protocol, has good compatibility and is convenient for programming.
5. Low voltage DC3.3V power supply with anti reverse-wiring protection, reversely-wired power supply will not damage the module but cannot work.
6. High isolation voltage, withstand voltage up to DC3000V.
7. Through-core current sensor or plit-core current sensor optional.
