The DIN Rail Power Meter is a standard metal rail for mounting circuit breakers and industrial control equipment in equipment racks. In addition, it acts as a mechanical support structure for different types of small electrical components.

　　At present, most terminal electric energy meters generally adopt the traditional wall-mounted installation method, which has the disadvantages of large size and inconvenient installation. The DIN rail type power meter is a new generation of miniature smart power meters for 380V/220V power distribution systems. Mounted on a standard 35mm din rail, the width matches the miniature circuit breaker. It can be easily installed in small distribution boxes.

　　DIN rail meters combine an industrial energy measurement system with intuitive installation, compact size, and a robust two-way communication protocol. These meters achieve an exceptional level of performance while remaining a low investment alternative, offering the following features:

　　1. The total active power is measured and re-included into the electrical energy;

　　2. RS-485 serial communication protocol;

　　3. Small size, the width is always 18mm, or a multiple of this value, very suitable for matching with miniature circuit breakers;

　　4. The lead seal has an anti-theft function;

　　5. DIN rail meters are superior to traditional meters in all measurable aspects.
