Product Overview
Single Phase Digital Din Rail Energy Meter is designed for accurate and stable energy measurement in residential, commercial, and light industrial applications.
It is built with a dedicated large-scale metering IC and SMT (Surface Mount Technology) production process, ensuring consistent measurement performance and long-term operational reliability.
The meter is powered directly from the voltage input circuit and does not require an auxiliary power supply. All cumulative energy data is stored in non-volatile memory, ensuring data retention during power loss.
