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

BJ195DCE DC Energy Meters are mainly used to
measure the energy consumption for different load
connected to it. DC energy consumption for the loads
like telecom BTS (Base Transceiver Stations), solar
panel and any applications need DC power parameter
monitor. The meter calculated energy data by
connecting appropriate shunts in the loads circuit. The
voltage drop across shunt is fed to DC energy meter
input terminals. The millivolts across shunts are
converted into current depending upon the shunt ratio
used in circuit.
The DC Energy Meter is a micro-controller based product that measures DC voltage and
currents, power, energy data and displays them on a 7-Segment five digital LED display
with auto scrolling. Blue Jay can set the parameters of DC energy meter from the
customer request.
As the world wide aim is necessary to reduce the power consumption and optimization the
use of available power/energy supplies. The application of smart energy meters are seen
as ideal solutions by providing monitoring the energy consumption in an accurate manner.

Introduction
