AC/DC Dual-mode LoRaWAN & RS485 DIN Rail Smart DC Energy Meter

Eastron DCM54 is an AC/DC dual-mode DIN rail smart meter capable of simultaneously performing high-precision measurement of electrical parameters in single-phase two wire AC systems (using external current transformers) and DC systems. Measured parameters include voltage, current, power, frequency, active energy, reactive energy, and bidirectional DC energy. Energy is measured in kWh and kvarh.

Eastron DCM54 smart energy meter integrates AC and DC metering into a single instrument and includes a built-in LoRaWAN wireless communication module, allowing direct data upload without an additional gateway. The product is also equipped with an RS485 (Modbus RTU) interface for convenient connection to local monitoring systems. The meter features a segment LCD screen (with white backlight) that cyclically displays AC/DC energy, network status, and battery state of charge (SOC). A built-in real-time clock and backup battery support event recording and alarm functions.

Eastron DCM54 smart energy meter is designed for photovoltaic energy storage systems, communication base stations, DC charging piles, industrial DC power supplies, and new energy microgrids. In PV storage systems, it simultaneously monitors inverter AC output and battery DC charge/discharge. For communication base stations, it centrally monitors AC backup power and DC loads, simplifying on-site wiring. For DC charging piles, it supports bidirectional metering, providing a reliable basis for billing. The product integrates AC/DC metering, LoRaWAN remote communication, and bidirectional energy detection, aiming to provide users with a simpler and more efficient bidirectional energy management experience.
