Three-phase electric energy meter DEM-6MC

RS-485residentialprepaid

The DEM-6MC multi-function wifi energy meter features high-accuracy power metering and monitoring, ideal for prepaid management systems in residential, industrial, and commercial applications. It integrates a class 0.2 precision measurement module for real-time acquisition of three-phase voltage, current, power, energy, current unbalance, and harmonic data. Measurement data is transmitted via RS485 or wireless modules (WIFI, 4G, Zigbee, LoRa, IoT) for centralized remote monitoring and management. - Class 0.2 high-accuracy energy metering; - Real-time measurement of voltage, current, power, etc. (including unbalance, 63rd harmonics); - Prepaid control: automatic tripping when credit runs out; - Supports power restoration via DI input or remote command; - Supports RS485 MODBUS-RTU and wireless communication (Wi-Fi, 4G, IoT, etc.); - Supports sound and light alarm, manual mute, and reset; Specifications: - Power grid mode: 1P2W, 3P3W, 3P4W - Power supply: AC/DC 85-265V, 45-65Hz - Consumption: ≤5VA - Data refresh frequency: 1S - Rate value: 100V/220V/380V - Overload: 1.2Un - Power consumption: 2%: 5%Uh; Uh100kΩ turns off - DO: 2 channels, Relay contact capacity: 5A@250VAC; 5A@30VDC - Communication: RS485, Modbus-RTU or Ethernet, Modbus-TCP/IP - Pulse output: 1 channel, pulse width 80ms, photoelectric isolation - Pollution degree: 2 - Overvoltage category: CATIII@277/480VAC - Insulation capability: 2kV AC RMS 1 minute, between input / output / case / power supply - Discharge immunity test: IEC-61000-4-2 level 4 @8kV - Fast transient burst immunity test: IEC61000-4-4 level 3 @Input 1kV; Power supply 2kV - Surge (Shock) immunity test: IEC61000-4-5 level 4 @Common mode: 4kV - Working temperature: -10°C ~ +55°C; RH 5% ~ 95% (non-condensation) - Storage temperature: -40°C ~ +85°C; RH 5% ~ 95% (non-condensation) - Demand record: Maximum monthly demand in the past three months - Multi-tariffs ratio: 4 sets rates, 12 segments - SOE record: 60 lists, (30 lists DI/DO SOE and 30 lists Alarm SOE) - Dimension: 110mm×108mmx66mm (W*H*D), 35mm Din-rail mounting
