The unit is low cost, easy-to-use, individual and multifunctional that enables to measure all the basic parameters required in an electrical installation and monitors electricity over and above basic metering. The entire range is very rugged and cost-effective. All these products are field proven and more than 100,000 units are active in service.
An electric meter, or energy meter, is a device that measures the amount of electric energy consumed by a building, tenant space, or electrically powered equipment. Electric utilities use electric meters installed at customers' premises to measure electric energy delivered to their customers for billing purposes
.1 Description DEM8900-1/DEM8900-2/DEM8900-3 (short form for DEM8900) is designed by adopting the updated microprocessor and digital signal processing technology, which can be applied for monitoring the electrical system. DEM8900 can measure and analyze the real time electrical parameters, such as I,kWh,kvarh., Meanwhile, DEM8900 has functions of multi-tariff,RS485 communication ( MODBUS protocol),analog output, remote input and electrical pulse output. All our instruments fulfill all important requirements and regulations concerning electromagnetic compatibility and safety isolation (IEC61000, IEC1010 standard and EN61010 standard). The devices have been developed, manufactured, and tested in accordance with Quality Assurance System ISO 9001. 1.2 Measured parameters Note 1. DEM8900-1 measure current, active energy, active power (optional, with analog output) 2. DEM8900-2 measure current, reactive energy, reactive power (optional, with analog output) 3. DEM8900-3 measure Current, active energy, reactive energy, active/reactive power (optional, with analog output) 1.3 EMC and Safety standard IEC61000-4-2 (GB/T17626.2) IEC61000-4-8 (GB/T17626.8) IEC61000-4-4 (GB/T17626.4) IEC61010-1 (GB/T4793.1). Exterior Size:91*91*72mm 0.5KGS.
BLUE JAY DC energy meters with a DC signal conditioner board combine high accuracy with high read rate and a wide range of isolated output options for computer interface and control. DC energy meter operation provides four full-scale current ranges 5.00A with 25mA resolution. The 5.000 A range measures can connect current shunt to expand the measure range. Voltage ranges from 5V with 25 mV resolution to 600.0 V with 5V resolution. All current and voltage ranges are factory calibrated, without recalibrating the meter. External current shunts are fully supported. Scaling is 75 mV - 5A, more than 5A will set transformer ratio from the front panel of the meter. The scalable readout is four full digits up to 9,999 counts. Shunt is remotely located for direct sensing. This allows the current carrying wires to take a more direct path to the large current and alleviates the need to route them through the meter case.
