LCD Display Three Phase Electric Meters with 3*20(80A Current
Active Energy Measurement
- Measure and display Phase A, Phase B, Phase C and total active
- Remote switch on/off alarm: the meter can send command at the
master station to switch on/off alarm based on the specific power
- Single-chip micro-computer control and fully digital metering and
smart anti-tamper protection;
- Three phases supply power at the same time, and the meter can work
properly only one phase has the power and it also can display the
loss of phase.
- RS 485 communication port;
- Display method: LCD screen with six integers and two decimals

With the development of reconstruction project for distribution
networks, traditional manual meter reading , which gradually
emerges its limitations , such as heavy workload, low efficiency,
high error rate etc., cannot meet the informatization and
modernization requirements of electric power management system
anymore. Therefore, the advanced remote meter reading system taking
the place of the manual will become an inevitable trend because of
its high reliability, low cost and easy to popularize.
Our electric meter has RS485 communication port to connect with the
data acquisition terminal equipment such as collector/ concentrator
so as to realize the function of remote meter reading, as shown in
the figure below.
6.1. Input/Output Function
The meter supports external signal input function, such as press
button and RF module.
This meter does not support impulse signal output by impulse like,
only impulse signal output by impulse light is supported
6.2. Error Alarming Function
The meter support error alarming function, once error detected, LCD
Displays error, to make it easier to learn the error source.
6.3. Parameter setting function
The meter supports parameter modification, the first time meter
electrified, the system will set up a default parameter list and
the users can modify the parameter according to their actual
requirements. The parameter setting function is only accessible for
the intermediate and higher level user, normal user have no right
to set parameters.
＊ Use only isolated tools.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the
meter can measure.
＊ Make sure the AC wires are installed correctly before activating
＊ Do not touch the meter connecting clamps directly with your bare
hands, with metal, blank wire or other material as you will have
the chance of an electricity shock and a possible chance for health
＊ Make sure the protection cover is placed after installation and
has been sealed.
＊ Installation, maintenance and repair should only be done by a
＊ Never break the seals or open the front cover as this might
influence the functionality of the meter.
＊ Do not through, drop, kick or other physical violence to the
meter as there are high precision components inside that will break
or make the meter measure inaccurate.
＊ Do not mount the meter in area's with harm gas, dust, mildew or
insects or on unstable surfaces.
