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.
.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)

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.

ML14xx is Multiload Monitor with 12 single phase load or 4 three phase load option. It measures important electrical parameters of multiple loads simultaneously in a single unit, eliminating the need and cost of multiple panel meters. It provides quick, easy and error free current connections with plug and play connectors. It measures real time electrical parameters like Active / Reactive / Apparent energy and power, current, THD, demand, max demand for each load. The instrument has 4 configurable relay outputs, which can be used for Limit / Pulse / Residual Current / 3Phase Load Health Monitoring / Tariff / RTC / Timer tripping or alarms. This instrument communicates with either MODBUS or Ethernet connection
