Product Description
Overview:
JSY-149 Din rail single-phase AC smart electric energy meter highly integrates measurement and digital communication technology, capable of measuring, collecting and transmitting single-phase AC electrical parameters. It can accurately measure single-phase AC electrical parameters such as voltage, current, power, forward and reverse electrical quantities and total electrical quantities. With 1 RS-485 communication interface, MODBUS-RTU protocol, with excellent cost-effectiveness.
JSY-149 can be widely used in energy-saving renovation, power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries, for remote monitoring of the current and power consumption of AC equipment.
Features:
1. Collect single-phase AC electrical parameters such as voltage, current, power and electric quantity etc.
2. Adopting dedicated measuring chips and effective value measurement methods, with high measurement accuracy.
3. With 1 RS-485 communication interface.
4. Standard Modbus-RTU communication protocol, which has 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, connecting the reverse power supply will not damage the module.
7. High isolation voltage, withstand voltage up to DC2000V.
