Gomelong is a professional manufactures of Two phase three wire modbus RTU energy meter.
Two phase three wire modbus RTU energy meter is utilized digital sampling technology and advanced SMT technology The meter has unbeatable accuracy and high reliability. It is designed and manufactured according to actual situations of resident usage of electricity. The two-phase voltage and current through the sampling circuit switched into signals and the signals into a two-phase energy measurement specific integrated chip. The specific IC put out pulse signals which are proportional to the measured two-phase power to drive the register, to achieve measuring two-phase eneray. At the same time, the energy meter output power test pulse with isolated optical coupler.
Smart meters are intelligent terminals in smart grids. They are no longer meters in the traditional sense of the word. In addition to the metering functions of traditional energy meters, smart meters are also used to meet the needs of smart grids and new energy sources.
First, the actual line voltage and current are sampled, and the power signal is generated by the UI multiplier; second, the U/f (voltage/frequency) converter is used to convert the power signal into a pulse signal with a certain frequency, and the pulse signal is converted by the counter Accumulated electricity consumption
