Guidelines for Din Rail Meters

1. What is a Din Rail Meter?

Din Rail Meters are electronic energy meters mounted on a DIN rail. They consist of a measuring unit, a data processing unit, and a communication unit, and provide energy measurement, data storage, real-time monitoring, and information exchange.

2. Differences Between Din Rail Meters and Traditional Meters

Small Size: They utilize a modular design with a width typically multiple of 18mm, allowing them to be installed in distribution boxes with miniature circuit breakers.

Easy Installation: They mount on standard 35mm DIN rails, eliminating the need for additional brackets, saving space and facilitating networking.

Diverse Functions: They support remote meter reading, time-of-use metering, harmonic analysis, abnormal power usage monitoring, and other functions. Some models also feature Ethernet or wireless communication.

High Accuracy: Active energy metering accuracy can reach 0.5S or Class 1, meeting electricity metering requirements.

III. Installation and Maintenance of Rail Meters

1. Installation Requirements

Select a standard 35mm DIN rail and ensure secure installation.

When wiring, ensure the correct connection of current and voltage circuits to avoid short circuits or open circuits.

Use shielded cable for communication lines to reduce electromagnetic interference.

2. Maintenance Tips

Regularly inspect the meter's appearance and terminals for loose connections.

Calibration is generally performed every 1-2 years to ensure meter accuracy.

Pay attention to communication status and promptly address data transmission anomalies.
