Industrial and Commercial Applications of DIN Rail Three-Phase Electric Meters

Industries and commercial establishments are heading towards efficient energy management to protect the environment and save enough for the future. DIN rail three-phase electric meters from Eastron Europe allow them to monitor energy usage and optimise consumption to reduce operational costs. Three-phase DIN rail meters from Eastron Europe, for example, the SDM630 Series, are widely used in factories, commercial buildings, EV charging stations, and renewable energy systems. Such metering devices allow seamless energy distribution and compliance with industry standards.

What is a DIN Rail Three-Phase Electric Meter?

A three-phase electric meter mounted on a standard DIN rail makes for an easy and space-efficient installation. They are deemed efficient measurement systems of three-phase circuits, with wide applications in industrial and commercial settings, compared to single-phase systems.

 Features and Applications of Three-Phase DIN Rail Meters

Having a sound understanding of the key features will help you to know where DIN Rail mounted meters are applied from industrial and commercial standpoints.

Here are the features described alongside the applications:

1.High Accuracy & Precision Measurement

DIN rail three-phase meters offer high accuracy, ensuring precise energy tracking and billing. Models such as the Eastron SDM630MCT provide Class 1 accuracy for voltage and current measurements.

2. Multiple Communication Protocols

Modern three-phase meters support various communication protocols such as:

  • Modbus RTU – Common in industrial automation
  • Modbus TCP - Common in commercial automation
  • M-Bus – Used for utility metering
  • RS485 – Enables remote data communication
  • Wi-Fi & Ethernet – For IoT-based energy monitoring
  • LoRaWAN – Wireless modulation

3.Real-Time Energy Monitoring

Meters like the Eastron SDM72D-M provide real-time tracking of:

  • Voltage and current per phase
  • Power factor
  • Active and reactive energy
  • Frequency measurements

4.Compact & Modular Design

DIN rail meters are built for easy integration into distribution panels, making them ideal for space-limited environments.

5.MID, Eichrecht, UL & IEC Certifications

Compliance with the Measuring Instruments Directive (MID), Eichrecht, UL-US-2555352-0, UL-CA-2541605-0 and IEC standards ensures reliability, accuracy, and legal billing compliance.

Industrial & Commercial Applications

Manufacturing & Factories

In industrial setups, three-phase meters monitor power-intensive machinery, helping manufacturers optimise energy usage and prevent overloads.

Commercial Buildings & Offices

Businesses use these meters to track energy consumption across different floors or departments, improving cost efficiency and sustainability.

EV Charging Stations

Accurate energy measurement in EV charger metering ensures proper billing and load management in public and private charging networks.

Renewable Energy Systems

Three-phase meters like the Eastron SDM630MCT-TCP integrate with solar panels and wind energy systems, providing precise energy export and import data.

Smart Grids & Utility Monitoring

Energy providers rely on these meters for automated energy distribution and demand-side management.

Benefits of Using a DIN Rail Three-Phase Meter

DIN rail 3-phase mounted meters from Eastron Europe, for example, SDM54-M, are designed primarily to help industrial and commercial sectors adopt a culture of responsible consumption. The benefits of using such mounted meters are elaborated below:

Cost Efficiency & Energy Optimisation

These meters help businesses minimise wastage and reduce electricity costs with real-time energy tracking systems.

Ease of Installation & Scalability

The modular DIN rail design allows easy expansion for future energy monitoring needs.

Remote Monitoring & IoT Connectivity

Advanced meters support cloud-based monitoring, enabling users to track energy consumption remotely through web applications.

Compliance with Energy Regulations

Meeting industry regulations ensures accurate billing and adherence to national energy efficiency standards.

Installation & Maintenance Best Practices

In order for the DIN rail mounted 3-phase meters to deliver at par with industrial expectations, they should be installed as per the instructions meted out by the engineers. Also, keep in mind the precautionary measures as per directions. That said, the installation process is quite seamless and easy - follow the steps mentioned below:

Installation Steps:

  1. Turn off the power before installing the meter.
  2. Mount the meter on a DIN rail inside the distribution board.
  3. Connect voltage and current inputs as per the manufacturer’s wiring diagram.
  4. Configure communication settings if required.
  5. Power on the system and verify meter readings.

Safety Precautions:

  • Always follow electrical safety guidelines.
  • Ensure proper grounding to prevent electrical hazards.
  • Use insulated tools when handling live circuits.

Maintenance Tips:

  • Regularly check for loose connections.
  • Calibrate the meter periodically for sustained accuracy.
  • Update firmware if remote monitoring features are used.

Common Troubleshooting:

  • Inaccurate reading? Check wiring connections.
  • No data communication? Verify protocol settings.
  • Display not working? Ensure proper power supply.
