Product Description DCEM-4MS Dual-channel DC energy meter is a highly integrated product for DC parameter measurement. When used with a shunt or external Hall sensor, it can accurately measure 1-2 channels DC voltages and 1-2 channels DC currents (with direction), power, total electricity, each single-circuit electricity, and other electrical parameters, and can be equipped with optional DI modules.DCEM-4MS has RS485 and supports MODBUS-RTU communication protocol, which can upload the collected data and equipment status. DCEM-4MS is widely used in electric power, communications, railways, transportation, environmental protection, steel, and other industries to monitor the current and power consumption of DC equipment.FeatureMeasurement and calculation functions such as DC voltage, current, power, and forward and reverse electric energy.Multi-rate electric energy metering functionMaximum demand measurement and demand time recordingMaximum value record: single-phase voltage, current, power maximum and minimum values, and occurrence timeTime-stamped event recordingpower freezeSupports RS485 interface MODBUS-RTU communication protocol, and one more RS485 port can be selected2-way switch input monitoring, 2-way relay output (optional)Supports second DC voltage and current input (optional)Various anti-interference measures.Convenient and flexible system wiring.Easy to install, 35mm standard DIN rail installation.Powerful data collection and processing capabilities.Intuitive Large-size LCD screen real-time measurement information.High security and good reliabilityA variety of anti-interference measures have been adopted during the design process to ensure stable operation in the power system environment. The electrostatic discharge immunity meets level 4; the electrical fast transient burst immunity meets level 4; the high voltage impact immunity meets level 4; the surge immunity meets level 3; the panel protection level meets IP54, and the shell protection level meets IP20.SpecificationPerformanceParameterEnter Measurement DisplayDistribution networkDCVoltageRating0-1000VOverload Measurement: 1.2 times Instantaneous: 10 times/1sImpedance>1 kΩ/V RatingDC Shunt:0-75mVcurrentHall current sensor:5A,20A,50A,100A,200A,300A,400A,500A optional OverloadMeasurement: 1.2 times Instantaneous: 2 times/10s Impedance<100mΩAccuracy levelClass 1 or 0.5Clock (optional):The daily error is less than 0.5 secondsDisplaySegment LCD displayPower supplyrangeAC/DC85V~265Vpower consumption≤4VAOutputDigital interfaceRS-485, MODBUS-RTU protocol (optional 2-Channels RS-458)Pulse outputOptional 1 channel active electric energy pulse output,1 channel second pulse outputDI input (optional)2 DI, dry contact modeRi<500Ω turns on, Ri>100kΩ turns offDI output (optional)2 DO relayrelay contact capacity: 5A/250V AC; 5A/30V DCEnvironmentWorking environment-25~55°C Altitude ≤2000m,98%RH, no condensation, no corrosive gasStorage environment-30~75°CSafetyWithstand voltageInput and power supply>4kV; input and output>4kV.power supply and output>4Kv.InsulationPower supply to shell > 5MΩDimensionApplicationThe DC energy meter can be used for various EV charging station applications from different brands to different KWh EV chargers.
