Direct measurement 3-phase energy meter 125 A with pulse output and RS485 with MID 412075

Three-phase energy meter – precise measurement and remote reading

This three-phase electricity meter, designed for direct connection, is a reliable solution for both installers and end users. It ensures accurate energy consumption measurement in three-phase circuits with currents up to 125A, and thanks to its communication interfaces, enables remote data reading and integration with monitoring systems. It complies with the MID directive requirements, guaranteeing legal metrological approval and measurement reliability.

Functionality and Application

The meter is ideal for use in commercial buildings, industrial facilities, and installations requiring precise energy consumption control. Thanks to its two-tariff measurement system, it allows for energy cost optimization by billing consumption across different tariff zones. The pulse output (S0) enables easy integration with building management systems (BMS) and other monitoring devices. The RS-485 interface ensures communication with remote meter reading systems (AMR).

Key Features and Benefits

• Direct measurement: Eliminates the need for additional current transformers, simplifying installation and reducing costs.
• Communication interfaces: Pulse output and RS-485 enable remote data reading and integration with energy consumption monitoring systems, allowing real-time cost control and consumption optimization.
• MID compliance: Guarantees legal metrological approval and measurement reliability, which is crucial for billing with energy suppliers.
• Two-tariff operation: Enables billing of energy consumption across different tariff zones, helping to reduce costs.
• Reverse rotation blocking: Protects against tampering and ensures fair energy consumption measurement.
• Robust construction: IP54-rated enclosure provides resistance to atmospheric conditions and mechanical damage. DIN rail mounting facilitates installation in electrical distribution boards.
• 6-module width: Compact dimensions allow easy installation of the meter in standard distribution boards.

The meter's maximum current (Imax) is 125 A, with a rated voltage L-L of 340 – 465 V and N-L of 197 – 265 V. The frequency range is 47 – 63 Hz, and the accuracy class is B. Communication is provided via the RS-485 interface and optical pulse output S0. The meter supports a two-tariff measurement system and has an IP54 protection rating.

This meter is an investment in precise measurement, energy cost control, and electrical installation safety. It is a robust and reliable device that meets the expectations of even the most demanding users.
