The rail mounted energy meter is a new generation of miniature intelligent energy meters used in 380V/220V terminal lighting systems. It adopts standard DIN35mm rail mounted design, modular structure design, and width matching with miniature circuit breakers, making it easy to install in the lighting box.
The electricity meter adopts LCD display, measures electrical energy and other electrical parameters, and can set parameters such as clock, tariff period, etc. It also has the function of outputting electrical energy pulses. RS485 communication interface can be used to achieve data exchange with the upper computer.
The rail mounted energy meter has the advantages of small size, high accuracy, good reliability, and easy installation. Its performance indicators meet the technical requirements of national standards GB/T 17215, GB/T 17883, and the power industry standard DL/T614 for energy meters. It is suitable for sub metering of electricity in government agencies and large public buildings, and can also be used for energy management assessment in enterprises and institutions.
The single-phase rail type energy meter is a new type of single-phase fully electronic energy meter developed by our company using microelectronics technology to measure electricity, imported large-scale integrated circuits, and advanced technologies such as digital processing technology and SMT technology. This electricity meter fully complies with the relevant technical requirements of GB/T17215.321-2008 national standard and IEC62053 standard for 0.5 level or 1 level single-phase electricity meters. It can directly measure the positive active energy in electricity metering, and display the total electricity consumption by LCD or meter; The LCD display can be equipped with an optional RS485 communication interface, which has the characteristics of convenient meter reading, high reliability, small size, light weight, beautiful appearance, advanced technology, and 35mm DIN standard rail installation; And it has good resistance to electromagnetic interference, low power consumption, high precision, high overload, high stability, and anti electricity theft. Long lifespan.
Three phase rail type energy meter,
So what are the main characteristics of three-phase rail type electric meters? Today, the editor will list them all and see if the rail type electric meter you see has all these functions:
1. Small size, space saving, and easy to install.
2. Precision measurement, anti electricity theft, and convenient management.
3. The rail type electrical energy adopts a modular design, with stable performance and strong anti-interference ability.
4. Instantly display the user's electricity load data.
5. One meter, one household for independent measurement, centralized display, without affecting other users.
6. The electricity meter is powered by three phases, and if any of them is missing, it can still work as usual.
7. Equipped with phase loss protection function, for example, for three-phase users, if there is a phase loss caused by power supply or relay failure, automatic phase loss protection will be carried out to ensure the normal operation of the user's three-phase equipment.
8. Use multiple data parameter encryption algorithms to ensure data security.
9. By designing lightning protection communication circuits, communication circuits, and meter circuits separately, the damage caused by lightning strikes to instruments is reduced.
10. The data acquisition module adopts a computer specific interface, which makes the transmission of signals more reliable.
11. The three-phase rail type energy meter has added a relay detection function inside, and the software directly monitors the working status of the relay online. The software can judge the quality of the relay on its own.
12. The three-phase track type energy meter uses a dedicated metering chip, which has high accuracy and long service life.
