RS485 three-phase rail mounted energy meter, as the name suggests, is an energy calculation table that can execute single rate electricity pricing. Therefore, it is often used in some enterprises, institutions, commercial residential users, and limited space three-phase electrical equipment that execute single rate electricity pricing. It can support far-infrared communication and is a new type of energy meter that meets the needs of different places and users. The biggest advantage of this energy meter is that it not only supports remote communication, but also displays the power level in the event of a power outage. It is equipped with a battery for use, which can be designed and modified according to the actual needs of customers.

The RS485 three-phase rail mounted energy meter adopts a liquid crystal LCD digital display screen, which realizes the display of numbers on the screen. The overall 8 is a number, and the first 6 is an integer plus two decimal places. Both positive and negative active power can be recorded and displayed. When reverse metering occurs, the reverse indicator light will immediately light up to indicate the effect. The phase failure LED alarm warning device is a newly added new type of warning effect. The power source of the electric energy meter comes from the three-phase power supply, which can ensure the accuracy of measurement even in the event of power outage or line interruption.
