Three-phase electric energy meter DEM-4MC

DIN railRS-485pulse output

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 5A/1A CT, it can use external current transformers to extend the current measurement range up to 999A. In addition to basic voltage, current, frequency, harmonic analysis 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 2.5kV, 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. Wide range of Application The DEM-4MC din rail 3 phase energy meter supports current rating up to 999A with the 100mA/333mV/ 5A/1A external CT connection. Besides, multi-DI/DO port configuration is available. Thus, it is widely used for 1 phase 2 wires, 3 phase 3 wires, 3 phase 4 wires systems in residential billing, room rental billing and industrial applications.
