Chapter 1 Product Overview
EGO700 Multi Function Power Meter For IOT is mainly applicable to the
distribution cabinet and switch cabinet in the high and low-voltage distribution system
lower than AC 650kV (phase voltage). It can communicate with RS485 / MODBUS
bus to manage the meter network and realize automatic control.
The product performance fully meets the relevant technical requirements of GB /
T 17215.322-2008 for active power level 0.5s and GB / T 17215.323-2008 for reactive
power level 2.
The product mainly realizes the following functions:
Full power measurement: three phase voltage, current, active power, reactive
power, apparent power, power factor, frequency, voltage and current angle, cable
temperature and residual current
Energy metering: bidirectional electric energy, historical electric energy
Demand function: real time demand, daily maximum demand and monthly
maximum demand
Power quality: 63th harmonic analysis, voltage and current content, THD,
imbalance;
Alarm: over voltage, under voltage, over-current, under current, phase loss,
frequency too high, frequency too low, power too high, switch value 1 off, etc
Data record: historical electric energy for lately 10 years, 12 months and 31 days
Event record of electric parameter maximum value: event record with time scale
and operation record
Communication: 1-way RS485 communication is provided as standard, 4G / Lora
can be selected for infrared communication, MODBUS, HTTP, Mqtt and other
communications are supported, and MODBUS custom register is supported
Switch value input: one active switch input is provided as standard
Temperature of cable: 4-way 0-150
℃
cable temperature measurement
Residual current: 1-way 0-8000ma residual current measurement
