Product Description

 

Product Description

DEM-4M3C wifi energy meter is designed for DIN-RAIL mounting, suitable for residential energy metering and smart energy projects. The Modbus-RTU and pulse output communication of the electric power meter allows seamless integration with data acquisition systems. Various sub-models are available, and prepaid (IC card) is optional. DEM-4M3C din rail energy meter can transmit data by wireless (4G/5G, Rolar, etc.). Moreover, extension modules are available in built-in and external these two versions.

 

The three-phase din rail electric power meter and electric energy meter adopt a pen segment LCD screen, which is a combined ACpower measurement terminal, and is a highly integrated product for AC parameter measurement applications. It has many functions, including measurement and calculation of three-phase AC power, power accumulation, harmonic analysis, voltage and current imbalance analysis, multi-rate energy measurement, maximum demand measurement, 4-channel switch input, and 2-channel relay output.

 

DEM-4M3C electric energy meter also provides a communication interface to connect with the computer monitoring system, supports the RS485 interface MODBUS communication protocol, and can upload the measured data and equipment status. This electric power meter can be widely used in electric power, communication, railway, transportation, environmental protection, petrochemical, steel, and other industries to monitor the power consumption of AC equipment.
