The single phase digital din rail energy meter adopts a dedicated large-scale integrated circuit and SMT (Surface Mount Technology) to ensure metering accuracy and operational reliability. Powered by voltage signals, it requires no additional auxiliary power supply and can still store the cumulative power value after power failure. With a compact and elegant appearance, light weight, a 5+1-digit wide-temperature LCD display, it supports 35mm standard rail installation and has a self-power consumption of less than 2W/5VA, making it suitable for various power metering scenarios.

Advantage
1.Multi-functional real-time monitoring:
The single phase digital din rail energy meter supports real-time display of voltage, current, power and electric energy values, allowing users to intuitively grasp the power consumption status and meet the needs of refined power management.
2.High-reliability design:
It adopts large-scale integrated circuits and SMT technology to reduce the risk of component failure; automatically saves the cumulative power value after power failure to avoid data loss and ensure the continuity of metering data.
3.Convenient installation and adaptation:
It complies with 18mm standard rail installation specifications, can be quickly integrated into various power distribution boxes, and is compatible with most power system installation scenarios.
4.Wide environmental adaptability:
It withstands an operating temperature range of -30°C~+55°C, environmental conditions with relative humidity ≤85%, and can resist the impact of corrosive gases, suitable for complex working conditions.
Main structure and working principle
The electrical energy consumed by the user is sampled through the divider, the signal on the divider, and sent to the amplifier and multiplier circuit. The product signal is output through the integration and V/F conversion,and through the logical frequency division circuit,drive LED display to measure electrical energy.
