AC Multi Circuit Energy Meter 4*3Phase Circuits

Multi Circuit Energy Meter DZS400

  • Measuring combination active power, reactive power composition of each circuit, four-quadrant reactive power of each circuit;
  • With load record of all parameters every hour;

  • Storage 12 clearing day energy data;

  • Measuring voltage, frequency, and instantaneous values of each electric parameters in each loop(current/voltage/active power/reactive power/power factor etc)






The DZS400 is an advanced, three-phase multi-loop networked multifunctional energy meter.

It is widely used in power distribution sites, energy management systems, and intelligent monitoring systems of different industries. 

It can monitor up to 4* three-phase circuits: current, voltage, frequency, active energy, reactive energy, four-quadrant reactive energy, etc.

Equipped 1-channel 485 communication interfaces to support standard DL/T645-1997/2007, Modbus RTU communication protocol.

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.
