LCD Display Three Phase Electric Meters with 3*20(80A Current Active Energy Measurement
MAIN FUNCTION:
- Measure and display Phase A, Phase B, Phase C and total active energy.
- Remote switch on/off alarm: the meter can send command at the master station to switch on/off alarm based on the specific power consumption.
- 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

METER UPDATE:
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.
EXTENDED FUNCTION:
6.1. Input/Output Function
Input Function
The meter supports external signal input function, such as press button and RF module.
Output Function
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.
Safety precautions:
＊ 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 the current/voltage.
＊ 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 damage.
＊ Make sure the protection cover is placed after installation and has been sealed.
＊ Installation, maintenance and repair should only be done by a certified electrician.
＊ 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.
