LoRA 3*Single Phase/Three Phase Meter

Wireless smart power meter DZS310-Lis a 3*Single Phase or 1*Three Phase Circuit Comprehensive Meter based on LoRa wireless communication technology.

Compact Size and High Accuracy

• Ultrathin dimension with only 37mm depth and metering accuracy up to class 1

• Making smart power distribution operation and maintenance possible in various projects, especially those concerning retrofit, industrial automation, data collection, large volume of data, geographical dispersion, low budget and difficult construction.

It can be flexibly installed in various types of distribution boxes to realize energy measurement, statistics and analysis for different areas and different loads.

Cloud Management, more intelligent

• Based on advanced LoRa wireless communication technology

LoRa spread spectrum modulation technology; 433MHz; RS-485 communication mode being supported simultaneously

• Safe and reliable self-organizing network technology

Adopting wireless Mesh networking module and with embedded self-organizing network protocol, networking will be fast and the module will work once it is power on. Supporting 7-level routers, its network covers more than 7KM. Link layer adopts intelligent collision avoidance algorithm with excellent anti-interference ability.

• Cloud management

The power operation and maintenance system uploads data from the user directly to the cloud through the public network. The data can be applied in central meter-reading, intelligent power distribution, energy management, smart factory system etc.;

Live Installation

• With din rail installation and no need to power off and no wire, costs will be saved and normal production activities will be guaranteed at the same time.


• Measuring all parameters: three phase voltage, current, line voltage, active power, reactive power, apparent power, power factor, frequency,  active energy, reactive energy   

• 1 interface* RS485      

• Modbus RTU communication protocol    

• 1* programmable energy pulse output  

• LCD display 






Wireless smart power meter DZS310-L is mainly used for measuring three-phase active energy in ow-voltage network with RS-485 communication function. As it can convert communication between wireless transmission and RS485 communication, it achieves immediate data reception and transmission and facilitates power monitoring, central meter-reading, power distribution operation and maintenance for users.

The LoRa Data Transmission Terminal is universal communication interactive equipment, which is designed and manufactured based on LoRa RF chip. It integrates two interfaces of industrial standard RS485 and supports a variety of protocols to realize data transmission between wired and wireless devices. It can be widely applied in the IOT, centralized metering and industrial control etc..

The Energy Management System acquires real-time energy consumption data from the acquisition terminal then calculates and stores the data from all sorts (i.e. water, electricity, gas, heating), subareas, sub items and sub time with mathematical method of summarizing and splitting etc. Then checking system, which accurately and quantitatively measures unit energy consumption, can be provided by monitoring and diagnosing the data. Thus energy saving management can be realized.
