The meter "white backlit liquid crystal suitable for reading" is a combined DC power measurement terminal, which is a highly integrated product for DC parameter measurement applications. The DC energy meter with a data logger can accurately measure 1 DC voltage and 1 DC (with direction) with an external shunt, power, total electricity, each single-way electricity, and other electrical parameters, and can be equipped with a switch output.
At the same time, the energy meter DC has an RS485 interface, supports the MODBUS-RTU communication protocol, and can upload the data collected by the measurement and the status of the equipment. The DC voltage electric alarm meter can be widely used in electric power, communication, railway, transportation, environmental protection, petrochemical, steel, and other industries to monitor the current and power consumption of DC equipment.
