The DEM-4MC three-phase rail-mounted energy meter is an ideal choice for residential billing, room rental billing, and industrial applications. With a width of 4 modules and a default 100mA/333mV CT, it can use external current transformers to extend the current measurement range up to 999A. In addition to basic voltage, current, frequency and other basic energy measurement functions, the DEM-4MC can optionally measure advanced parameters such as demand record and voltage and current imbalance detection. The DEM-4MC features CATIII-300V voltage rating and and withstand voltage of 2kV, ensuring safety and reliability in complex electrical environments. The DEM-4MC provides real-time voltage and current readings through an LCD screen and supports RS485-RTU and pulse output ports. It can be expanded with multiple DI/DO ports, offering users a comprehensive energy management solution. Compliant with international standards IEC61557 and IEC62053, the DEM-4MC is suitable for the diverse needs of residential, public facility, and industrial scenarios.

Description

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

The three-phase rail type electric energy meter adopts a pen segment LCD screen, which is a combined AC power 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 unbalance analysis, multi-rate energy measurement, maximum demand measurement, 4-channel switch input, 2-channel relay output. 19D-34C 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 product 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.
