Compared with ordinary and general energy meters, three-phase electronic energy meters with 485 communication have better performance. Its power supply adopts the three-phase power supply method, so in the process of use, whether any line in the three-phase power supply is cut off or there is a problem, it will not affect the accuracy of measurement and the normal and stable use of the energy meter. During the measurement process, both forward and reverse electricity can be recorded in the meter, while reverse electricity is recorded in the forward direction. During operation, the passive pulse output light of the equipment will light up, and the pulse indicator light will indicate that it is in working condition.

The three-phase electronic energy meter with 485 communication comes with the function of supporting far-infrared communication, which facilitates specific operation and use. When there is a power outage or power outage, the power-off display function of the energy meter will immediately start to ensure the normal operation of the equipment, and it will be matched with a dedicated battery to provide power. The phase failure LED alarm prompt system enables the device to issue an alarm when there are problems during operation and work, serving as a reminder to reduce and avoid accidents and problems, as well as their impact. Its power on/off function can also be controlled remotely through a computer.
