Description The technical performance of the energy metering module fully meets the relevant technical requirements of the class 1 active energy meter in the IEC62053-22 national standard. It can directly and accurately measure the voltage, current, power, power factor, and power factor in the three-phase AC power grid with a rated frequency of 50Hz or 60Hz. Electricity parameters such as electric quantity and total quantity. The electric energy metering module has a set of ESD protection RS485 interface, MODBUS-RTU communication protocol, which is convenient to connect with various AMR systems. It has the characteristics of good reliability, small size, light weight, beautiful appearance and convenient installation.
Specification Three-phase AC input Voltage range: 100v, 220v, etc. optional Current range: 5A, 20A, 50A, 100A, etc. optional, with external open current transformer model optional Signal processing: using dedicated metering chip, 24 bit AD Overload capacity: 1.2 times the range is sustainable; instantaneous (<200ms) current 5 times, voltage 1.2 times the range is not damaged. Input impedance: voltage channel>1KΩ/V, current channel ≤100mΩ Data format: "n,8,1", "e,8,1", "o,8,1", "n,8,2" can be set by software Communication rate: The baud rate of the communication interface can be set to 1200, 2400, 4800, 9600bps; the default is 960bps Communication data: multiple electrical parameters such as voltage, current, power, electric energy, etc. |
