Direct Current DC &AC Power Metering Module RS485 Modbus
JSY-MK-229 single-phase AC/DC electric energy meter is a power monitoring product that integrates AC and DC measurements, can complete power measuring, electrical parameters collection and data transmission. It can accurately measure single-phase AC parameters (voltage, current, power, power factor, frequency, electrical quantity, etc.) and DC parameters (voltage, current, power, electrical quantity, etc.). With 1 RS-485 communication interface, completely isolated circuit, small size, simple interface, and easy to embed into various devices that need to measure electricity consumption, with excellent cost-effectiveness.
JSY-MK-229 can be widely used in energy-saving transformation, AC/DC charging station, power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries, and for remote monitoring of the use of AC and DC equipment.
Features:
1. Collect AC/DC electrical parameters such as voltage, current, power, power factor and electrical quantity.
2. Adopting dedicated measuring chips and effective value measurement methods, with high measurement accuracy.
3. With 1 RS-485 communication interface.
4. Modbus-RTU protocol has good compatibility and is convenient for programming.
5. Using 12-36VDC power supply.
6. Diverters of different specifications optional.
