RS485 Energy Meter


RS485 energy meter is used to measure the single-phase AC active power with 50Hz frequency by RS485 line remotely.


1. Firstly, read the meter ID, each meter ID is the serial number on the name plate, such as No.401411210001.

2. Meter ID, total electricity consumption, meter constant can be read remotely by the software and AMR device, and the meter relay can be remote controlled on or off too.

3. The infrared device, the RS485 can be used to limit the power capacity (the set of limit power capacity cannot exceed the range in the below form), if the used power capacity is larger than this limited power capacity, the meter will switch off to stop power supply, and power again 2 minutes later. If don’t need this function of limited power capacity, just set the limited power capacity as zero.
