Products Description
The electronic single-phase AC energy meter is a fully digital device designed for accurate measurement of both forward and reverse active and reactive energy in single-phase AC systems. In addition to precise energy metering, the device supports intelligent energy management based on crew dispatch or duty cycles, making it well-suited for applications in locomotives and rail vehicles.
With its fully electronic architecture, the meter offers high reliability, stable performance, and resistance to electromagnetic interference. It enables real-time monitoring and efficient energy usage tracking, contributing to operational safety and cost-effective power management in modern railway systems.
