Single Phase Two Wire DIN Rail Meter--DDS1226

Single Phase Two Wire DIN Rail Meter--DDS1226 function

 

Active energy measurement: It can accurately measure the active energy consumed in the circuit and provide basic data for energy usage statistics.

Single energy direction: It can identify and process the energy flow measurement in a single direction and clarify the direction of energy transmission.

1TE width: In terms of physical structure or installation size, it has a 1TE width specification, which is suitable for corresponding space installation requirements.

Modbus interface: The Modbus communication interface is configured to realize data interaction and transmission with devices that support this protocol.

Applicable to AC electric vehicle charging stations and any sub-item billing applications: Its functional characteristics enable it to play a role in AC electric vehicle charging station scenarios and various applications that require sub-item metering of electricity charges.

MID certificate: Obtaining the MID (Measuring Instruments Directive) certification certificate indicates that the product complies with relevant metrology regulations and other requirements.

Convenient and efficient installation: It adopts DIN rail installation, without complex wiring or additional fixing structure, and can be directly mounted on the standard rail, saving installation time and space, especially suitable for batch deployment in compact scenes such as distribution boxes and control cabinets.

Simple wiring and material saving: Only two wires, the live wire and the neutral wire, need to be connected. Compared with multi-wire meters, it reduces the wiring steps and wiring complexity, while saving cable material costs, and it is easier to troubleshoot faults during later maintenance.

1. What scenarios is this single phase two wire DIN rail meter suitable for? ​
This meter is suitable for a variety of scenarios, such as residential and small commercial places, and is used to accurately measure the energy consumption in single-phase AC circuits. In some environments where space requirements are high and the meter needs to be installed conveniently, its DIN rail installation method has obvious advantages.

2. What is the accuracy level of the meter?
The accuracy levels of single-phase two-wire DIN rail meters of different brands and models vary, and the common ones are 0.5 and 1. The 0.5 level accuracy means that the meter is within ±0.5% when measuring electric energy; the error of the 1 level accuracy is within ±1%. ​

3. What communication functions does it have and what are the communication protocols? ​
Most single-phase two-wire DIN rail meters have RS485 communication interfaces. In terms of communication protocols, common ones are Modbus RTU, DL/T645 - 2007, etc. Modbus RTU is widely used and has strong compatibility, facilitating data exchange with various control systems, SCADA systems and energy management systems.
