Dimension(218mm×145mm×72mm):
(1) The electric meter should be installed indoors and installed on the wall or in the meter box. The electric meter should be basically vertical when installing.
(2) The voltage to be connected should meet the rated operating voltage, and the current should not exceed the maximum rated current.
(3) In the case of power failure, the wiring should be strictly as shown in the wiring diagram.
(4) The electric meter is fixed on the meter box with three screws.
Working Principle
Measured AC voltage and current have been sampled and transported to professional metering chip, after digital processing, they have been changed to the pulse signal, which in direct proportion to active power, and then sent to microprocessor. Microprocessor would accumulate the pulse signal according to the tariff, then get total power and tariff power and put them in register. At the same time, the microprocessor finishes the function of display and changeover with external messages. Please take attention to the Figure 1
LoRaWAN communication interface:
Using LoRaWAN communication for meter reading and parameter setting. When meter reading, remote meter data transmission software provided by our company can be used for meter reading
and parameter setting. It is also possible to design a software and hardware system that fully
complies with the protocol requirements for meter reading and parameter setting according to the
power industry standard DL/T 645-2007 (supporting part of the communication protocol). Please take attention to the followig points when handle meter reading and parameter setting:
a. Parameter setting, please just setting items which refers to the certain meter
