Reliable Energy Measurement with Advanced Communication and Monitoring

Accurate electrical energy monitoring is essential for understanding consumption, identifying inefficient equipment and managing operating costs. The Finder 7M.38.8.400.0312 provides detailed measurement of active, reactive and apparent energy, together with instantaneous electrical parameters such as voltage, current, power factor and frequency. These measurements help electrical engineers, facilities managers and energy professionals assess installation performance and identify opportunities for improved energy efficiency.

The meter's bidirectional measurement capability is particularly valuable in installations where electrical energy can flow in both directions. Solar photovoltaic systems, battery energy storage installations and other distributed energy applications can benefit from separate monitoring of imported and exported energy. Its dual-tariff capability also supports installations where consumption must be recorded across different tariff periods.

For connected energy management, the integrated M-Bus interface enables communication with compatible supervisory and metering systems, while the S0 pulse output provides a conventional interface for energy data acquisition. The infrared communication port offers further integration possibilities, and NFC technology allows compatible smartphones to access meter information and perform supported configuration tasks. These features make the 7M.38.8.400.0312 suitable for both local monitoring and remotely managed electrical installations.

The meter is designed for installation on a standard 35 mm DIN rail and occupies approximately three modular spaces. Its backlit display supports convenient reading of measurements, while the sealable terminal shield helps protect the integrity of metering connections. With MID-certified active energy measurement and direct current handling up to 80 A, it provides a dependable platform for electrical submetering, energy reporting and industrial consumption analysis.
