EMC-D3b/EMC-D3b-485 - 1

EMC-D3b ENERGY MULTIFUNCTION COUNTER EMC-D3b-485 AVAILABLE MODELS EMC-D3b: 3-phase energy counter with 7+1 digit display. 1 digital input and two digital pulse output for kWhr and kVArhr. EMC-D3b-485: 3-phase energy counter with 7+1 digit display, 1 digital input, two digital pulse output for kWhr and kVArhr, EIARS485 serial communication port, Modbus RTU protocol. Both are manufactured in DIN rail mounting case 6 modules 17.5 mm. INTRODUCTION The EMC-D3b models allows the local or remote counting of the energy, with the help of a serial interface. It is possible to set the instrument to count in 3 different mode (Normal / Total and partial / Timeband). Also the instrument is equipped with a digital input which can cover different function. See the digital input section for more information. The auxiliary power supply is taken from same Voltage inputs (VL1 and VL2), used for measuring. It’s available as option the instrument for single phase networks. OPTIONS and ACCESSORIES options: - internal CT's (not for direct line insertion) (order with -t suffix) - current inputs for ... /1A current transformer (order with /1A suffix) - current sensor for low current measures (Max 15 Amp) (specify when ordering) - power supply and measuring voltages other than the standard (specify when ordering) - power supply separated from measuring voltage (specify when ordering) - single phase network (power supply is taken from VL1 and neutral) (specify when ordering) MEASURED PARAMETERS Parameters showed in counter mode three phase system active energy three phase system reactive energy three phase system apparent energy Parameters showed in meter mode phase voltages phase to phase system voltages phase currents phase power factors phase active powers phase reactive powers phase apparent powers frequency Unit of measure [kWhr] [kVArhr] [kVAhr] unit of measurement [V-kV] [V-kV] [A-kA] [W-kW-MW] [VAr-kVAr-MVAr] [VA-kVA-MVA] [Hz] Identifying abbreviations kWh kVArh kVAh initial identification V L2-N V L3-N V L2-L3 V L3-L1 A L2 A L3 PF L2 PF L3 W L2 W L3 VAr L2 VAr L3 VA L2 VA L3 These parameters are available only on EMC-D3b-485 model and readable only by RS485 interface.
