E1-3P DC Multifunction Meter

E1-3P DC Multifunction Meter

The E1-3P DC Multifunction Meter is a combined DC power measurement terminal, which is a highly integrated product for DC parameter measurement applications. It can accurately measure 1 DC voltage and 1 DC current (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 device 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 device 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.
