  • Product Overview

DDZY2397 single-phase fee controlled smart energy meter (single-phase IoT energy meter (din rail) is a full-digital intelligent energy meter developed by our company. It adopts a SOC highly integrated chip. In addition to the active energy metering function, it also has multiple functions such as online power display, intelligent anti-theft electricity, overload control, and remote centralized meter reading. The data

is transmitted to the corresponding platform through the wireless network of LoRaWAN/NB-IoT/Cat.1(4G)/Bluetooth. It has the advantages of high precision, low power consumption and good stability. Widely used in single-phase alternating current metering occasions such as various residences, intelligent buildings, markets and malls, collective dormitories, and schools.
  • Functions and features
​1. Measuring positive and negative active energy. It can measure, store, and display the operating parameters and status of the current electric energy meter such as voltage, current, power, power factor, frequency, etc. With overload protection function;
2. Remote power off and power transmission function: send a command of power off through RS485/LoRaWAN/Cat.1(4G) and other communication methods to cut off the user load circuit. Or send a command of power transmission to connect the user load circuit;
3. Active upload/two-way transparent transmission function: actively upload data to the corresponding platform through the LoRaWAN/Cat.1 (4G) wireless network, the default interval is 4 hours (settable);
4. The communication protocol conforms to DL/T645-2007 "Communication Protocol for Multi-function Electric Energy Meter";
