As the name suggests, a single-phase 485 communication energy meter is an energy meter that adds a far-infrared communication interface and power on/off function. The advantage of this design combination is that it can remotely control the user's electricity consumption through networking. Of course, this can be planned and modified according to the actual needs and usage of the customer. The electric energy meter uses passive pulse output to indicate its operation during normal use. When the pulse indicator light is on, it indicates that the equipment is in working condition, and when the light is off, it indicates that the equipment is in shutdown condition. In order to improve the user experience, a power outage display function has been added, which can ensure normal and stable operation through the use of the battery in case of insufficient power or power outage.

The display screen of the single-phase 485 communication electricity meter adopts a liquid crystal LED display screen, which has a backlight function. It can clearly see the numbers and other contents on the display screen even in very dark environments, and can fully display 8 as a number, 6 integers plus 2 decimal places, with high accuracy and precision.
