Single phase Two Wire DIN Rail meter Manufacturer
High-precision metering: Using a dedicated energy metering chip and digital sampling processing technology, it can accurately measure the active energy in a single-phase AC power grid with a rated frequency of 50Hz or 60Hz, and the accuracy level can usually reach 1.0 or higher.
Convenient installation: 35mm DIN standard rail installation, in line with DIN EN 50022 standard, or front-panel installation (mounting hole center distance 63mm), can be easily placed in various lighting boxes and lighting cabinets, convenient for centralized installation and management.
Small size: The width is generally a multiple of 18mm, such as the width of a 1P meter does not exceed 18mm, and the width of a 4P meter is 72mm. The structure is modular, matching the miniature circuit breaker, saving installation space.

What level of measurement accuracy can a single-phase two-wire DIN rail meter achieve?
Common accuracy levels are 1.0 and 2.0. Most products that comply with the IEC62053-21 international standard or GB/T 17215 related national standards can achieve accurate measurement. 1.0 level accuracy means that under specified conditions, the measurement error is controlled within ±1%, and the active energy consumption in the single-phase AC power grid can be accurately counted.
How does the meter achieve accurate energy measurement?
Use a dedicated energy measurement chip with digital sampling and processing technology. For example, Zhuhai Guoce's products sample voltage and current in real time, and the chip calculates active energy based on the sampled data. At the same time, the SMT process is used to improve product stability and reliability and reduce measurement deviations caused by component problems.
What anti-interference measures does the product have to ensure stable operation?
As a professional manufacturer of single-phase two-wire DIN rail meters, Reallin usually adopts multiple anti-interference designs. In terms of hardware, electronic components with strong anti-interference ability are selected, and the circuit board is reasonably laid out to reduce signal interference. In terms of software, filtering algorithms are set to remove clutter signals. Some products also have anti-static, lightning protection, and anti-electromagnetic interference capabilities. For example, some products have passed relevant EMC (electromagnetic compatibility) tests and can effectively cope with complex electromagnetic environments.
