Smart Multi Phase RS485 Power Analyzer Kwh Watt Hour Dual Circuits DC Electric Power Energy Meter with Hall Sensor CT or DC Shunt for EV Charger Solar System

Product Description

DCEM-4MS Dual-channel DC energy meter is a highly integrated product for DC parameter measurement. When used with a shunt or external Hall sensor, it can accurately measure 1-2 channels DC voltages and 1-2 channels DC currents (with direction), power, total electricity, each single-circuit electricity, and other electrical parameters, and can be equipped with optional DI modules.
DCEM-4MS has RS485 and supports MODBUS-RTU communication protocol, which can upload the collected data and equipment status. DCEM-4MS is widely used in electric power, communications, railways, transportation, environmental protection, steel, and other industries to monitor the current and power consumption of DC equipment.
