Wenzhou Legy Electric Meter Technology Co., Ltd., established in 2002 in Wenzhou, China, is a professional manufacturer specializing in electronic energy measurement solutions. As an experienced China supplier, our factory develops and produces Single Phase DIN Rail Meter products featuring compact modular design, high measurement accuracy, and flexible communication capabilities.
Designed for residential, commercial, and small industrial power distribution systems, the Single Phase DIN Rail Meter provides reliable electricity monitoring in limited installation spaces. With more than 20 years of electrical manufacturing experience, we combine advanced electronic measurement technology, strict quality control, and international certifications including CE and ROHS to deliver efficient metering solutions for global distributors, electrical contractors, and system integrators.
A Single Phase DIN Rail Meter is a compact electronic electricity measurement device designed for single-phase AC power systems and installed directly onto a standard 35mm DIN rail. It uses digital sampling technology and microelectronic measurement circuits to accurately monitor electrical energy consumption and operating parameters.
Compared with traditional panel-mounted meters, this modular meter requires less installation space and can be easily integrated into distribution boxes, control cabinets, and automation systems. It is widely used for residential sub-metering, commercial electricity management, and single-phase equipment monitoring.
The Single Phase DIN Rail Meter adopts a standard DIN EN50022 35mm rail mounting structure, allowing direct installation together with circuit breakers, contactors, and other modular electrical components. The compact 18mm or multi-module width design helps optimize cabinet space and simplifies electrical panel layout.
Using advanced digital sampling and SMT manufacturing technology, the meter provides stable and accurate measurement performance. It supports Class 1.0 or Class 0.5 accuracy levels and can measure active energy, voltage, current, instantaneous power, and other electrical parameters.
The Single Phase DIN Rail Meter supports RS485 communication with Modbus RTU protocol for integration with energy management systems. Optional WiFi, GPRS, or 4G communication modules enable remote data monitoring, automatic meter reading, and smart energy management applications.
Equipped with LCD or LED digital display, the meter provides clear energy consumption information through 5+2 or 6+1 digit readout. Users can quickly check accumulated energy data and operating status without additional testing equipment.
The meter is designed with durable ABS/PC housing and stable electronic components, supporting wide operating temperature ranges from -40°C to +75°C. It is suitable for various indoor distribution environments and industrial electrical cabinets requiring long-term operation.
For projects where electrical cabinet space is limited, the Single Phase DIN Rail Meter provides an efficient alternative to conventional meters. Its modular structure allows more measuring points to be installed within the same distribution panel, improving space utilization.
The snap-on DIN rail mounting method eliminates drilling and additional mounting accessories. Electrical installers can complete installation quickly, reducing labor costs and minimizing wiring errors during project deployment.
By monitoring individual apartments, offices, equipment circuits, or renewable energy systems, the meter provides accurate consumption data for billing management, energy analysis, and operational optimization.
Wenzhou Legy Electric Meter Technology provides customized solutions including current ratings, communication modules, display options, and housing configurations to meet different regional standards and project requirements.
Single Phase DIN Rail Meter is widely installed in apartment distribution boxes and residential electrical panels for individual unit energy measurement. It supports accurate consumption monitoring and helps property managers improve electricity billing efficiency.
In office buildings, retail stores, and commercial facilities, the meter enables independent electricity monitoring for different tenants or departments, supporting transparent cost allocation and energy-saving management.
The meter is suitable for monitoring single-phase motors, lighting systems, control circuits, and auxiliary equipment in factories. Accurate energy data helps operators identify unnecessary consumption and improve efficiency.
Single Phase DIN Rail Meter can be integrated into small photovoltaic systems and single-phase EV charging stations to measure energy generation, consumption, and charging power, supporting modern energy management.
The meter is mounted directly onto a standard 35mm DIN rail inside the distribution cabinet. After fixing the device position, connect the incoming and outgoing terminals according to the wiring diagram. For communication models, connect the RS485 or wireless module and complete parameter configuration before operation.
Regular maintenance includes checking terminal connections, verifying communication performance, and inspecting display operation. Keeping the electrical cabinet clean and dry helps ensure stable measurement accuracy and extends service life.
