Summarize

Electronic three-phase high-power watt-hour meter, used in power supply departments, enterprises, agricultural power equipment in active energy metering, the table uses imported special large-scale integrated circuit, 16-bit a/D conversion, digital multiplier, digital sampling processing technology and SMT process, manufacturing of new high-power watt-hour meter. And the use of liquid crystal display, with infrared, RS485 communication function of the energy meter, in line with MODBUS-RTU

(Default: 9600.N.8.1) The standard DL/T 645-2007 communication protocol effectively implements the remote hypertable function

The meter is accurate, stable, reliable, has good anti-electromagnetic disturbance, low power consumption, high accuracy, anti-theft, wide range, long life and so on. This table conforms to standard GB/T 17215.321-2008 and ensures high current accuracy for calibration in production

Working principle

This energy meter adopts three-phase power supply mode, and can work normally under the three-phase power supply of high power 160kwh When the energy meter works, the voltage and electricity flow through the circuit are respectively sampled and sent to the large-scale application-specific integrated circuit, which is converted into electric energy pulse after the digital multiplier operation, and the liquid crystal meter is driven to measure electric energy
