Single-phase 2 Way Power Metering Module Modbus TTL Electric Energy Metering PCBA
The JSY-MK-194T single-phase two-way electric energy metering module highly integrates measurement and digital communication technology, which can measure, collect and transmit single-phase AC power parameters. It can accurately measure two-way single-phase AC voltage, current, power, power factor, frequency, electricity and other electrical parameters. With 1 TTL level interface, completely isolated circuit, small size, simple interface, easy to be embedded in various equipments that need to measure power consumption, highly cost-effective.
JSY-MK-194T can be widely used in energy-saving transformation, EV charging station, power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries to monitor the current and power consumption of AC equipment.
Features:
1. Collect single-phase two-way AC electrical parameters such as voltage, current, power, factor, frequency and electricity etc.
2. Using dedicated measuring chips and effective value measurement methods, with high measurement accuracy.
3. With 1 TTL communication interface, compatible with 5V/3.3V interface.
4. With Modbus-RTU protocol, which has good compatibility and is convenient for programming.
5. High isolation voltage, withstand voltage up to DC3000V.
