Single Phase AC Electricity Energy Meter 4G Wireless Intelligent Control Smart Power Meter
JSY-MK-1039 is an single phase smart energy meter that can measure, capture and transmit single-phase AC electrical parameters. It can accurately measure single-phase AC voltage, current, power, forward and reverse electricity. Built in 2 RS-485 communication interfaces and 1 4G communication interface, can read electrical data from other products of JSY Technology (up to 16 products), with MODBUS-RTU protocol.
JSY-MK-1039 can be widely used in industries such as energy-saving renovation, power, communication, railway, transportation, environmental protection, petrochemical, steel, etc., for remote monitoring of current and power consumption of AC equipment.
Features:
1. Collect single-phase AC electrical parameters such as voltage, current, power and energy etc.
2. Using dedicated measurement chips and effective value measuring methods, with high measurement accuracy.
3. Built in 4G communication module with 2 RS-485 interfaces.
4. Modbus-RTU protocol, with good compatibility and is convenient for programming.
5. RS-485 communication interface with ESD protection circuit.
6. Wide working voltage AC80~265V, with anti reverse-wiring protection function, wiring the power supply reversely will not damage the module.
7. High isolation voltage, withstand voltage up to DC2000V.
