Three Phase Four Wire DIN Rail CT Meter--D30162 Feature
Active energy metering: used to accurately count the actual energy value of work done in the circuit, which is the basic data source for electricity billing and energy efficiency analysis, and helps to grasp the real power consumption of electrical equipment.
One-way or two-way power direction: can identify whether the power transmission is one-way (such as traditional power supply, only from the grid to the user) or two-way (such as distributed power grid connection, power can flow in the opposite direction from the user to the grid), and adapt to a variety of energy interaction scenarios.
2TE width: generally refers to the width requirements for ensuring power-related data transmission and interaction under 2TE bandwidth conditions (which may be associated with specific communication, transmission and other technical standards), affecting the efficiency and stability of information transmission.
Line loss measurement: through monitoring and calculation, the amount of power loss caused by resistance and other factors in the transmission of power lines is obtained, providing a basis for the formulation of power grid energy-saving optimization and loss reduction strategies.
CE certificate: related power metering, monitoring and other equipment meet the requirements of European unified safety, health, environmental protection and other directives.

Three Phase Four Wire DIN Rail CT Meter--D30162 manufacturer
Easy and efficient installation: Standardized DIN rail installation is adopted, without complicated screw fixing and wiring. The installation can be completed by simply inserting the meter into the 35mm standard rail, which greatly reduces the construction difficulty and time cost.
Safe and accurate measurement: With the help of external current transformer (CT), large current is proportionally converted into small current measurement, which meets the precise measurement needs of large load scenarios such as industry and commerce, and can also prevent large current from flowing directly through the meter, reducing the risk of equipment damage caused by overload and short circuit, and improving safety.
FAQ
1. How to troubleshoot the three-phase meter without communication failure?
Check whether the RS485 wiring is reversed (A/B lines are reversed) or virtual connection; confirm that the meter reading system parameters are consistent with the meter.
How to select the CT ratio of the three-phase CT meter?
Select according to 1.2 times the sum of the maximum current of the three-phase load. If the three-phase load is unbalanced, select the CT according to the maximum phase current.
3. What scenarios are applicable?
Industrial three-phase motor, production line energy consumption monitoring; commercial complex three-phase power supply household metering (such as office buildings, hotels); multi-circuit monitoring of temporary power distribution boxes at construction sites.
